An environmental engineer wants to examine the permeability of different soils to determine the best natural containment system to protect groundwater from pollutants. The engineer tests four different soil samples, places them into a wet column, and pours 50mL of water over each sample. The engineer records the total amount of water that moves through the column as well as the total amount of time for the water to fully percolate through the soil. The data from the study are shown below.
Which of the following best describes why the engineer chose to calculate the permeability of the soil sample in the experimental design in order to evaluate a natural containment system to protect groundwater?

Answer:

zero off your workpiece so you can work from a datum, usually the centre of your work on a lathe. change your tool to a drill and drill a hole to a size smaller than your thread diameter, change out your tool for a threaded tap and away you go.

I'm not sure which part they want but I'd say ensure your tool is set to the right height, you have the tool lines up where you want to cut and that you have calculated the speed you need to cut at safety. Drill a hole before you tap though.

If you have a CNC lathe you just set the programme to do the processes and tool change for you.

The first step to cutting internal threads on an engine lathe is to make calculations so that the thread will have proper dimensions.

The technique of thread cutting on the lathe results in a helical ridge with a consistent section on the workpiece.

To work from a datum, often the center of your work on a lathe, zero off your workpiece. Use a drill to create a hole that is less in diameter than the thread, then switch to a threaded tap and carry on.

One would advise making sure your tool is adjusted to the appropriate height, that it is lined up where you want to cut, and that you have determined the speed you must cut in order to be safe. Before you tap, drill a hole.

With a CNC lathe, you can simply program the machine to perform the processes and tool changes for you.

Therefore,  to do this, make a series of cuts with a threading toolkit that matches the needed thread form.

Boosting the strain rate or decreasing the temperature has the effect of raising the flow stress and decreasing ductility. The less uniform elongation before necking begins is what causes the poorer ductility; however, significant plastic flow may still be seen within the necked region.

Note that the primary distinction between yield strength and tensile strength is that the former refers to the lowest stress at which a material would permanently deform, whilst the latter refers to the highest tension at which a material will withstand before failing.

A stepped uniaxial bar is subjected to forces. The length and area of cross-sections of the two elements are asked to be written. The stiffness matrix of the given information is to be calculated.

Consider a stepped uniaxial bar subjected to forces as shown in the below diagram. The above bar has two different areas of cross-section and lengths. Hence, the bar can be divided into two elements with different areas and lengths.

Let us consider Element 1:

Here, \(l_1\) = Length of element 1

\(A_1\) = Area of cross-section of element 1

Let \(P_1\) and \(P_2\) be the forces applied on Element 1 and Element 2 respectively.

In general, the element stiffness matrix can be written as \(k = AE / Le\), where A is the area of the cross-section, E is the modulus of elasticity, and Le is the length of the element.

Let us calculate the stiffness matrix for Element 1. The stiffness matrix of Element 1, \(k_1\) is given by: 

\(k_1 = (A_1E_1 / l_1) * [1, -1; -1, 1]\)

Let us consider Element 2:

Here, \(l_2\) = Length of element 2

\(A_2\) = Area of cross-section of element 2

The stiffness matrix of Element 2, \(k_2\) is given by:

\(k_2 = (A_2E_2 / l_2) * [1, -1; -1, 1]\)

Now, we need to find the stiffness matrix of the complete bar. Let us consider k as the stiffness matrix of the complete bar. Then, \(k = [k_1 + k_2]\) is the stiffness matrix of the complete bar.

The complete stiffness matrix of the given problem is given by: \(k = [A_1E_1/l_1 + A_2E_2/l_2] * [1, -1; -1, 1]\)

Hence, the stiffness matrix of the given problem is given by \([A_1E_1/l_1 + A_2E_2/l_2] * [1, -1; -1, 1].\)

For a laminar flow through a pipe, the pressure drop over the length of a smooth pipe will be less compared to that in a rough pipe, if all other flow conditions remain the same.

Pressure drop in a pipe is directly proportional to the length of the pipe, density, flow velocity, and the friction factor. It is inversely proportional to the diameter of the pipe. The laminar flow is a flow condition in which fluid flows in parallel layers without mixing. A rough pipe has the internal roughness, which results in increasing the friction factor of the pipe.

Thus, the pressure drop in a rough pipe is high as compared to a smooth pipe with no internal roughness. The smooth pipe is free from any internal roughness, which means that it is having low frictional resistance as compared to a rough pipe. Therefore, the pressure drop in a smooth pipe is less compared to that in a rough pipe, if all other flow conditions remain the same.

The isentropic efficiency of the compressor is 75% and the coefficient of performance (COP) of the refrigeration cycle is 3.08.

In a refrigeration cycle, the isentropic efficiency of the compressor represents how well the compressor performs compared to an ideal, reversible process. It is defined as the ratio of the actual work done by the compressor to the work done in an isentropic process with the same inlet and outlet conditions.

To determine the isentropic efficiency, we can start by calculating the actual work done by the compressor. The power consumed by the compressor is given as 2.3 kW. Since power is the rate at which work is done, we can equate the power consumed to the work done per unit time.

Work done = Power consumed = 2.3 kW

Next, we need to determine the work done in an isentropic process. The isentropic efficiency is defined as:

Isentropic efficiency = Actual work done / Isentropic work done

Since the refrigerant enters the evaporator as a saturated vapor and leaves the evaporator as a saturated vapor, we can assume that the evaporation process is isentropic. Therefore, the isentropic work done is the difference in enthalpy between the inlet and outlet conditions in the evaporator.

Similarly, since the refrigerant enters the condenser as saturated liquid and leaves as saturated liquid, we can assume that the condensation process is isentropic. Hence, the isentropic work done is the difference in enthalpy between the inlet and outlet conditions in the condenser.

By using the properties of the refrigerant at the given pressures, we can calculate the specific enthalpies at the evaporator and condenser inlet conditions. The difference between these values gives us the isentropic work done.

Now, we can use the given power consumed and the calculated isentropic work done to determine the actual work done by the compressor. Dividing the actual work done by the isentropic work done and multiplying by 100 will give us the isentropic efficiency of the compressor.

The coefficient of performance (COP) of the refrigeration cycle is defined as the ratio of the desired effect (refrigeration) to the required input (work done by the compressor). The COP can be calculated as:

COP = Refrigeration effect / Work done by the compressor

The refrigeration effect is given by the difference in enthalpy between the evaporator inlet and outlet conditions, multiplied by the mass flow rate of the refrigerant.

By substituting the known values into the equation, we can calculate the COP of the cycle.

A 12 V battery is connected to a 100 Ω resistor and a capacitor. We have to determine the capacitance needed so that the voltage across the capacitor does not exceed a certain value.

Let us solve each part of the question separately. To determine the value of capacitance needed so that the voltage across the capacitor never exceeds 200 V, we can use the formula. I is the current in the circuit, t is the time interval, V is the maximum voltage, and C is the capacitance.

Here, we need to find the maximum current that can flow in the circuit without exceeding 200 V. We can use Ohm's law to find V = IR => I = V/R = 12/100 = 0.12 Therefore, the capacitance needed C = (It) / V = (0.12 × t) / 200For example, if we want the voltage across the capacitor to never exceed 200 V for 0.1 second, the capacitance required would C = (0.12 × 0.1) / 200 = 6 × 10^-5 F or 60 μF(b) To determine the value of capacitance needed so that the voltage across the capacitor never exceeds 20 V.

The maximum average normal stress in each of the links is: σ = (25lbs) / (1/32 sq. in.) = 1600 psi Since the stress is determined by the cross-sectional area, and not the direction of the force, the stress is compressive for both links.

To determine the maximum average normal stress in links CD and BE, we will first calculate the cross-sectional area of the links and the area of the pins. Then, we will divide the force P by these areas to find the stress in each link and identify whether it is tensile or compressive.
1. Cross-sectional area of links CD and BE:
A = width × height = (1/8) × (1/4) = 1/32 in²
2. Diameter of pins at C, D, B, and E:
D = 1/4 in
Since both links have the same cross-sectional area, they will experience the same normal stress.
3. Calculate the maximum average normal stress in links CD and BE:
σ = P/A = (50 lbs) / (1/32 in²) = 1600 psi
As there is no information provided on the direction of force P, we cannot determine if the stress in each link is tensile or compressive.
