It will take approximately 15 days for the crop to use the 3.6 inches of available water. The correct option is B.

The time it takes for a crop to use a certain amount of water depends on the crop's water usage rate, which is typically measured in inches of water per day. In this case, we know that the crop has 3.6 inches of available water. If we divide this amount by the crop's water usage rate, we can determine how long it will take for the crop to use all of the available water.

To calculate how long it will take the crop to use the 3.6 inches of available water, you need to know the crop's daily water consumption rate. In this case, the crop uses 0.24 inches of water per day. To find out how many days it will take to use up the 3.6 inches of available water, simply divide 3.6 inches by 0.24 inches per day:

When selecting materials for use as furnace linings, several factors need to be carefully considered. Two important factors are:

Temperature Resistance: Furnaces operate at high temperatures, and the chosen lining material must have excellent temperature resistance to withstand the extreme heat. Different furnaces may require different temperature capabilities, so it is crucial to select a lining material that can withstand the specific operating temperature range. Factors such as melting point, softening point, and thermal conductivity of the material should be evaluated to ensure it can handle the heat without deteriorating or deforming. High-temperature-resistant materials, such as refractory ceramics (e.g., alumina, silica, zirconia), refractory metals (e.g., molybdenum, tungsten), or specialized heat-resistant alloys, are commonly used for furnace linings.

Chemical Compatibility: Furnaces often involve various chemical processes and environments, such as oxidation, reduction, acidic or alkaline atmospheres, or exposure to corrosive gases. The selected lining material must be chemically compatible with these conditions to prevent degradation or chemical reactions that could compromise the integrity of the lining. It is important to consider factors such as resistance to chemical attack, stability in different atmospheres, and potential reactions with the process materials or by-products. Suitable lining materials may include refractory materials that are chemically inert or have specific chemical resistance properties, such as high-alumina refractories, silica-based refractories, or certain types of specialty coatings.

By carefully evaluating temperature resistance and chemical compatibility, the selection of a suitable lining material can ensure optimal performance, longevity, and safety of furnace operations.

Answer:

Directly proportional to voltage but inversely proportional to resistance

Explanation:

The law mentions that current is directly proportional to voltage but inversely proportional to resistance. At constant resistance, current increases as voltage increases and vice versa. At a constant voltage, the current decreases as resistance increases and vice versa.

Answer:

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them. Mathematically, this can be expressed as:

I = V/R

Where:

I is the current flowing through the conductor in amperes (A)

V is the voltage across the two points in volts (V)

R is the resistance between the two points in ohms (Ω)

This equation shows that if the voltage (V) is increased while the resistance (R) stays constant, the current (I) will also increase. Conversely, if the resistance (R) is increased while the voltage (V) stays constant, the current (I) will decrease.

This relationship is fundamental to the behavior of electric circuits, and is used extensively in circuit analysis and design.

Based on the given information, including the flow rate, composition, pressure, temperature, and velocity of the process stream, we can calculate the diameter of the pipe using Kay's rule.

Kay's rule is a method used to estimate the diameter of a pipe for a given process stream. It consider factors such as flow rate, composition, and velocity to determine an appropriate diameter. To apply Kay's rule, we need to determine the phase density of the mixture, which can be calculated using the ideal gas law and the composition of the stream.
First, we calculate the partial pressure of hydrogen and butene using the given composition. Then, by assuming ideal gas behavior, we can calculate the density of the mixture at the given pressure and temperature. With the flow rate and velocity provided, we can use Kay's rule formula, which relates the diameter to the flow rate and velocity, to determine the required diameter of the pipe.
However, without the specific composition information, such as molecular weights and compressibility factors, it is not possible to perform the detailed calculations and provide an accurate diameter value using Kay's rule in this context. The calculation requires additional data to determine the mixture density and apply Kay's rule effectively.

Answer: Ethanol

Explanation:

A 60Hz, 0.5-HP single-phase motor in a washing machine (120V RMS) has an efficiency of 78% at full load (rated output power) and a power factor of 0.72 lagging.

To find the line current, first determine the real power (P) using the formula P = HP × 746, where HP is 0.5. This gives P = 373W. Since efficiency is 78%, the input power (Pin) is P/0.78 = 478.21W. Now, use the power factor (0.72) to find the apparent power (S) by dividing Pin by the power factor: S = 478.21/0.72 = 664.18 VA. To find the line current (I), divide the apparent power (S) by the voltage (120V): I = 664.18/120 = 5.53 A.
The reactive power (Q) can be found using the formula Q = S × sin(arccos(0.72)), resulting in Q = 664.18 × sin(arccos(0.72)) = 536.65 VAR. In summary, the line current is 5.53 A, the reactive power is 536.65 VAR, and the apparent power is 664.18 VA.

The theoretical fracture strength of the brittle material is estimated to be approximately 165.6 MPa when a stress of 1300 MPa is applied and fracture occurs by the propagation of an elliptically shaped surface crack of length 0.29 mm and tip radius of curvature of 0.004 mm.

To estimate the theoretical fracture strength of a brittle material given the information provided, we can use Griffith's theory of brittle fracture. According to this theory, the fracture strength of a brittle material can be expressed as:

σ_f = (2Eγπa)^0.5

where σ_f is the fracture strength, E is the elastic modulus, γ is the surface energy per unit area, and a is the length of the elliptically shaped surface crack.

To calculate the fracture strength, we need to first determine the surface energy per unit area of the material. For glass, a typical value of surface energy is around 1 J/m^2.

Given the length of the elliptically shaped surface crack (a) is 0.29 mm, and the tip radius of curvature is 0.004 mm, we can calculate the crack area (A) as follows:

A = πab = π(0.29/2)(0.004)

A ≈ 5.67 x 10^-7 m^2

Next, we can calculate the elastic modulus (E) of the material. For glass, the elastic modulus is typically around 70 GPa.

Substituting these values into the equation for fracture strength, we get:

σ_f = (2Eγπa)^0.5 = [2(70 x 10^9)(1)(π)(0.29 x 10^-3)]^0.5

σ_f ≈ 165.6 MPa

An aluminum rod is press fitted onto an aluminum collar. The collar has an inner radius of 1 cm and an outer radius of 2 cm. Given the rod has a diameter of 1.01 cm and the young's modulus of aluminum is 69 GPa, determine the following :

1. the interference value, i

2. the radial pressure at the interference of the collar and the rod

3. the maximum effective stress in the collar

4. if the yield strength of aluminium is 200 MPa and assume a safety factor of 1.5, will the aluminium collar break

Solution:

Given :

Inner radius of the collar = 1 cm

So, inner diameter, \($d_1$\) = 2 cm

Outer radius of the collar = 12 cm

So, outer diameter, \($d_2$\) = 4 cm

The aluminium rod diameter, d = 1.01 cm

Now, from the figure, we can see that there will be no interference and so the rod will easily insert inside the collar.

1. So, the interference , i =0

2. The radial pressure is also 0.

3. There will be no stress developed. So the maximum effective stress is 0

4. The collar will not break

The local isentropic stagnation conditions in front of the shock and estimate the stagnation pressure sensed by the pitot tube.

a) To evaluate the local isentropic stagnation conditions in front of the shock, we can use the isentropic relations for a perfect gas. The isentropic relations relate the properties of a gas across a shock wave. Given the altitude of 12 km and the provided pressure and temperature of the surrounding air (19.4 kPa and -56.45 °C), we can calculate the local isentropic stagnation conditions.

First, we need to convert the temperature from Celsius to Kelvin:

T = -56.45 °C + 273.15 = 216.7 K

Using the ideal gas equation, we can calculate the density of the surrounding air:

ρ = P / (R * T)

Where P is the pressure, R is the specific gas constant, and T is the temperature.

For air, the specific gas constant R is approximately 287 J/(kg·K).

ρ = 19.4 kPa / (287 J/(kg·K) * 216.7 K)

After performing the calculation, we obtain the density of the surrounding air.

Now, using the isentropic relations, we can determine the isentropic stagnation conditions ahead of the shock. These conditions can be obtained by relating the Mach number (M) and the local conditions (P, ρ, T) to the isentropic stagnation conditions (P0, ρ0, T0).

The specific heat ratio (gamma) for air is approximately 1.4.

M0 = M * √(γ * R * T0 / (2 * γ * R * T))

Where M0 is the isentropic Mach number and T0 is the isentropic stagnation temperature.

Using this equation, we can solve for T0 and calculate the isentropic stagnation temperature.

Similarly, we can calculate the isentropic stagnation pressure (P0) using the relation:

P0 = P * (1 + ((γ - 1) / 2) * M^2)^(γ / (γ - 1))

By substituting the known values, including the calculated density (ρ), pressure (P), and temperature (T), we can obtain the isentropic stagnation pressure sensed by the pitot tube.

b) To estimate the stagnation pressure sensed by the pitot tube, we can consider that the pitot tube measures the stagnation pressure, which is the total pressure (P0) ahead of the shock. Therefore, the calculated isentropic stagnation pressure (P0) from part a) represents the stagnation pressure sensed by the pitot tube.

By following these calculations, we can evaluate the local isentropic stagnation conditions in front of the shock and estimate the stagnation pressure sensed by the pitot tube.

The amount of depreciation for the second full year, using the double-declining-balance method, is $23,750.

The double-declining-balance method is an accelerated depreciation method that allows for larger depreciation expenses in the early years of an asset's life. To calculate the depreciation using this method, we first need to determine the asset's straight-line depreciation rate.

Calculate the straight-line depreciation rate:

Straight-line depreciation rate = 1 / Estimated life in years

In this case, the estimated life is given as "L years or 21,000 hours." Since the question asks for the depreciation for the second full year, we can assume that L is equal to 2. Therefore, the straight-line depreciation rate would be:

Straight-line depreciation rate = 1 / 2 = 0.5

Calculate the double-declining-balance rate:

Double-declining-balance rate = 2 x Straight-line depreciation rate

Double-declining-balance rate = 2 x 0.5 = 1

Calculate the depreciation expense for the second full year:

Depreciation expense = Book value at the beginning of the year x Double-declining-balance rate

The book value at the beginning of the second year would be the cost of the machine minus the accumulated depreciation for the first year. Since the machine has an estimated residual value of $56,000, the cost of the machine would be $95,000 - $56,000 = $39,000.

Depreciation expense = $39,000 x 1 = $39,000

However, since the question asks for the depreciation for the second full year, we need to consider the depreciation expense for the first year as well. Using the same method, the depreciation expense for the first year would be $39,000 x 1 = $39,000.

Therefore, the depreciation expense for the second full year would be $39,000 - $39,000 = $0.
