Calculate the torque requirements for SAE 5.8 Class Bolt having a size of M24 x 3 UNC

(a)250 kg of water at 1 bar and 35°C is turned into wet steam at 7 bar (x = 0.95). Given at 1 bar hf = 417 kJ/kg, hfg = 2258 kJ/kg, Tsat = 100°C and at 7 bar hf = 697 kJ/kg, hfg = 2067 kJ/kg, Tsat = 165°C. Determine the energy required.

(b)Determine the mass of dry saturated steam at 1 bar that must be added to 500 kg of water at 20°C to achieve a final water temperature of 45°C. Given; hf = 417 kJ/kg, hfg = 2258 kJ/kg. Tsat = 100°C.

Suppose that in a machining operation of multidirectional FRPs you are getting

high principal (cutting) forces. Which action would you take to reduce the

principal forces? Why?

(a) Reduce cutting speed

(b) Increase rake angle

(c) Reduce depth of cut

(d) Increase clearance angle

(e) All of the above

A frictionless air compressor operates between 200 kPa and 6 MPa. The inlet is at 25°C. Compared to operating adiabatically, what is the energy-input (e.g. power) savings by cooling it with a polytropic exponent of 1.16? Answer in kJ/kg (i.e. kJ of energy saved for every kg of air compressed).

Correct answer is 9.23 kJ/kg; please show steps and thank you!

Rub wool on the Styrofoam cup and hold it over tiny bits of paper on the lab table. What happens to the paper?

Put down some dark paper and a pile of salt and observe the interaction with the charged cup. What happens to the salt?

Consider the fundamental forces: gravity, electromagnetic, as observed with the interactions with salt and pepper. How does this demonstrate the relative strengths (which is stronger?) of these fundamental forces?

Rub the balloon with the wool cloth (or with your own hair). What kind of charge does the balloon acquire? Bring the charged balloon near the bits of paper or salt. Will it “pick up” tiny bits of paper? Yes Observe how distance affects the interactions. What difference does distance make?

Charge it up again and press against a wall made of sheetrock (not brick or stone). Will it stick to the wall? No Go to the sink, turn on the water so that there is a small, steady stream. “Charge up” your plastic tube and hold it close to the top of the stream of water. What happens and why?

Now rub the plastic tube with a square cut from a cooking bag. Write a procedure that you can use to determine if the plastic tube has acquired a net positive or a net negative charge from the cooking bag. (you can use some of the other materials).

Bring the plastic tube charged with the cooking bag near the aluminum can. What happens to the aluminum can when the tube charged from the cooking bag is held near it?

An air-conditioning system operates at a total pressure of 1 atm and consists of a heating section and an evaporative cooler. Air enters the heating section at 15°C and 55 percent relative humidity at a rate of 30 m³/min, and it leaves the evaporative cooler at 25°C and 45 percent relatively humidity. Using appropriate software, study the effect of total pressure in the range 94 to 100 kPa and plot the results as functions of total pressure

7-9. Give two (2) piping materials with their corresponding schedule # and its application that is available in market today?

10. Give one (1) standard used for piping materials and state one (1) provision regarding that standard?

A beam of steel having square cross section of 20x20mm2

having E =
200 GPa is subjected to an axial (P) load of 20 kN, Torsional (T) load
of 60 Nm and Transverse (F) load of 0.60 kN as shown in Figure. Solve
each load independently for both element A and B existing at the top
and side surface of the beam respectively and determine:
a) State of stress against each load condition for both element A
and B
b) Draw Mohr’s Circle where applicable for each state of stress for
both element A and B
c) Determine the principal planes and the principal stresses,
d) Draw the orientation of the Principal Stresses
e) The stress components exerted on the element obtained by
rotating the given element counterclockwise through 30
degrees.
