The final temperature of air when expanded isentropically from 1425 kPa and 477°C to 100 kPa in a piston-cylinder device using the average specific heats from the ideal gas property tables is 315.5 K.

To determine the final temperature of air when expanded isentropically from 1425 kPa and 477°C to 100 kPa in a piston-cylinder device, we need to use the ideal gas law and the equation for isentropic expansion.
Firstly, we can use the ideal gas law to calculate the initial specific volume of air:
V1 = R*T1/P1
where V1 is the specific volume, R is the specific gas constant, T1 is the initial temperature (477°C = 750 K), and P1 is the initial pressure (1425 kPa).
V1 = 0.1989 m^3/kg
Next, we can use the equation for isentropic expansion to calculate the final specific volume of air:
V2 = V1*(P1/P2)^(1/gamma)
where V2 is the final specific volume, P2 is the final pressure (100 kPa), and gamma is the ratio of specific heats (1.4 for air).
V2 = 1.0265 m^3/kg
Finally, we can use the ideal gas law again to calculate the final temperature:
T2 = P2*V2/R
T2 = 315.5 K

The technician B is correct in this case since a turbocharger should not be operated at an engine oil pressure lower than 30 psi.

A turbocharger is a device that increases the efficiency of an engine by forcing air into it at a higher pressure. It increases the engine's power and efficiency by supplying it with additional oxygen.Turbochargers are used in both petrol and diesel engines. They are most commonly found in large diesel engines.

It is also used in motorsports, where it is used to improve engine efficiency and power output.Turbochargers are lubricated by engine oil, and most turbochargers have their lubrication system. A turbocharger cannot be operated at an engine oil pressure lower than 30 psi, which can cause damage to the engine's parts.

A turbocharger's lifespan is determined by how well it is maintained, as well as the quality of the oil being used. It is advised to keep your vehicle serviced and your oil changed regularly to keep your turbocharger running smoothly.

A divided-highway-ends sign indicates that the divided highway on which a driver is traveling will come to an end. This sign serves as a warning to motorists that they will be transitioning from a divided highway.

The purpose of a divided-highway-ends sign is to inform drivers of the upcoming change in road conditions. Divided highways are designed to enhance safety by separating opposing lanes of traffic, reducing the risk of head-on collisions and providing controlled access points. However, there are instances where a divided highway may come to an end, typically due to changes in road design or infrastructure. When drivers encounter a divided-highway-ends sign, they should be prepared for several changes in road conditions. Firstly, the physical barrier or median that separated opposing traffic will cease to exist, and drivers will need to adjust their driving behavior accordingly. Drivers should pay close attention to any accompanying signage or road markings that indicate the new road conditions. It is important to follow any posted instructions, adjust speed accordingly, and be prepared for possible changes in traffic flow or road configuration. A divided-highway-ends sign alerts drivers that they are approaching the end of a divided highway and will be transitioning to a regular undivided roadway. Motorists should be prepared for changes in traffic conditions, exercise caution, and adhere to any new signage or road markings to ensure a safe and smooth transition.

The capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.

A DC series circuit can be defined as a type of circuit in which all of its resistive components are connected end to end, so as to form a single path for the flow of current.

This ultimately implies that, the same amount of current flows through a direct current (DC) series circuit.

Mathematically, the capacitive reactance of a DC series circuit is given by this formula:

\(X_C = \frac{1}{2\pi fC}\)

Where:

From the above formula, we can deduce that the capacitive reactance of a DC series circuit is inversely proportional to both frequency and capacitance. Thus, the capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.

In conclusion, a capacitor would influence a simple DC series circuit by blocking the flow of direct current (DC) through it.

where x is the capital investment in millions of dollars.

differentiate the function Q(x) with respect to x.

\(dQ/dx = d/dx(2500x^(5/2))\)

Using the power rule of differentiation, we have:

\(dQ/dx = (5/2) * 2500 * x^(5/2 - 1)dQ/dx

= 6250x^(3/2) `dQ/dx

= 6250x^(3/2)`\)

which gives us the effect on the output if an additional capital investment of $1 million is made.

Note: To estimate the effect on the output if an additional capital investment of $1 million is made, we substitute x with x+1 in the expression for `dQ/dx`. This gives us the new output and the increase in output due to the additional investment.

Explanation:

The values of t for which each given signal is guaranteed to be zero are:

(a) t > -2

(b) t < -2

(c) t < -2

(d) t < 1

(e) t < 9

To determine the values of t for which each given signal is guaranteed to be zero, let's analyze each case individually:

(a) x(1 - t):

In this case, we substitute (1 - t) for t in the original signal x(t). Since x(t) = 0 for t < 3, when we substitute (1 - t) for t, we get:

x(1 - t) = 0 for (1 - t) < 3

Simplifying the inequality, we have:

1 - t < 3

t > -2

Therefore, for the signal x(1 - t) to be guaranteed to be zero, t must be greater than -2.

(b) x(1 - t) + x(2 - t):

Here, we consider the sum of two signals: x(1 - t) and x(2 - t). Since both individual signals are guaranteed to be zero for certain ranges of t, their sum will also be zero within those ranges. Specifically, for this sum to be zero:

x(1 - t) = 0 and x(2 - t) = 0

For x(1 - t) to be zero, we need (1 - t) > 3, which simplifies to:

t < -2

For x(2 - t) to be zero, we require (2 - t) > 3, leading to:

t < -1

Therefore, for the sum x(1 - t) + x(2 - t) to be guaranteed to be zero, t must be less than -2.

(c) x(1 - t)x(2 - t):

In this case, we multiply two signals: x(1 - t) and x(2 - t). To guarantee that their product is zero, both individual signals need to be zero for the same range of t. Therefore:

x(1 - t) = 0 and x(2 - t) = 0

Following the same reasoning as in part (b), we find that for x(1 - t)x(2 - t) to be guaranteed to be zero, t must be less than -2.

(d) x(3t):

In this case, we substitute 3t for t in the original signal x(t). Since x(t) = 0 for t < 3, when we substitute 3t for t, we get:

x(3t) = 0 for 3t < 3

Simplifying the inequality, we have:

t < 1

Thus, for the signal x(3t) to be guaranteed to be zero, t must be less than 1.

(e) x(t/3):

Here, we substitute t/3 for t in the original signal x(t). Since x(t) = 0 for t < 3, when we substitute t/3 for t, we get:

x(t/3) = 0 for t/3 < 3

Simplifying the inequality, we have:

t < 9

Therefore, for the signal x(t/3) to be guaranteed to be zero, t must be less than 9.

Substituting the given values in eq[2], we haveHconv = 20× 1.3× (135 - 27) = 3434 WNow, rate of heat loss due to radiation is given by the relation,Hrad = ε × σ × A × (Ts4 - Tsur4)...[3]where, ε is the emissivity of the surface, σ is the Stefan-Boltzmann constant, Ts is the surface temperature and Tsur is the average surrounding surface temperature.Substituting the given values in eq[3], we haveHrad = 1× 5.67×10-8× 1.3× (135 + 273)4 × (135 + 273 + 20)4 = 345.15 WThus, substituting the values of Hconv and Hrad in eq[1], we get the total rate of heat loss from the surface in watts asH = Hconv + Hrad= 3434 + 345.15 = 3780.15 WTherefore, the total rate of heat loss from the surface is 3780.15 W.
