While having a discussion, Technician A says that a coolant position sensor attached to the throttle body on the air inlet senses how many degrees the throttle plate is open. Technician B says that an air charge temperature sensor senses how many degrees the throttle plate is open. Who is correct? A only, B only, Both A and B, Neither A nor B

Briefly describe one of the method of incorporating fibers into matrix (i.e. fiber reenforced composite manufacturing method).

One kilogram of water is contained in a piston-cylinder device at 100 degC. The piston rests on lower stops such that the volume occupied by the water is 0.835 m3. The cylinder is fitted with an upper set of stops. When the piston rests against the upper stops, the volume enclosed by the piston-cylinder device is 0.841 m3. A pressure of 200 kPa is required to support the piston. Heat is added to the water until the water exists as a saturated vapor. Find the final specific volume (v4 = vg). Please show steps for interpolation.

A potential wind turbine location has an average wind speed of 5 m/s at a height of 10 m.

A) Assuming a standard wind friction coefficient of 1/7, what is the average wind power per area at the proposed tower height of 80 m?

B) If the proposed turbine has a cut-in speed of 4 m/s and a furling speed of 20 m/s, how many hours per year is the windmill not spinning (assuming Rayleigh statistics)?

C) Estimate the yearly power output (in MWh) for a turbine with a 100 m diameter and a generator rate at 2500 kW.

19. 4.5 lbm of water at 158 ^oF is mixed with 8.3 lbm of water at 30.9 ^oF. If the specific heat of water is 0.8 BTU/lbm-^oR, find the resulting temperature of the mixture in ^oF.

State your answer to one decimal place. Example: 63.5

20. 2.4 lbm of water at 136 ^oF is mixed with 9.1 lbm of water at 44.9 ^oF. If the specific heat of water is 0.8 BTU/lbm-^oR, find the sum of the change in entropy, in BTU/^oR, for the 2.4 lbm of water and 9.1 lbm of water.

State your answer to four decimal places. Example: 0.6357

The state at the beginning of compression of an air-standard Diesel cycle is fixed by p1 = 100 kPa and T1 = 310 K. The compression ratio is 18 and the cutoff ratio is 1.5. Determine: (a) the maximum temperature, in K. (b) the pressure at the end of the expansion, in kPa. (c) the net work per unit mass of air, in kJ/kg. (d) the percent thermal efficiency

A spring loaded piston cylinder device contains 3 kg of carbon dioxide which can be assumed to be an ideal gas. The system is heated from 110 kPa, 23C to 1100kPa, 305C. What is the work done during this process? What is the heat transfer during this process?

Nitrogen undergoes an isothermal process from 100 kPa to 500 kPa, T = 300K. How much specific work was required for this process?

You are looking to purchase the DeWalt air compressor. Assuming the compressor operates (outputs) air at 90psi and at 110F. If the atmospheric pressure is 0 psig and the atmospheric temperature is 65F, how much free air will the compressor consume in cubic feet (ft3 )/Minute to handle the 5 standard cubic feet per minute (SCFM)? • DeWalt Specifications -- 1.6 HP electric engine gets the job done. High-pressure motor with consistent draw requirements can be run with a 12-Gauge or higher extension cord that is under 50 ft. 200 psi maximum pressure enables long air-tool run time Delivers 5 SCFM at 90 psi for quick recovery time

An industrial machine weighing 1000 lb is supported by springs with a static deflection of 0.20 inches. The machine has a rotary unbalance of 20 lb / in. If this machine is mounted on a large concrete block weighing 2500 lb and the stiffness of the springs or supports under the block is increased so that the static deflection is still 0.20 in, what will be the dynamic amplitude?

Write a review paper of one measurement technique (any device you feel interested in or have experience with), which could be what I have learned in Measurement Engineering course (Mechanical Engineering : uncertainty, probability and statistics, basic circuits, ac and dc, adc dac conveter, 1st and 2nd order systems, tmeperture measurement).
The main content should include how it operates, its application, changes in design with time, and future direction. Although I have to focus on recent and future development.

Would you give me any examples of devices or suggest essay topics with temperture measurement ?

Air flows through a short duct with a smooth inside surface and gradually changing flow area. The measured flow rate is equal to 288 lbm/min. At the duct inlet, the temperature is equal to 82 deg F, and the pressure is equal to 15 psia. The inlet velocity is equal to 924 ft/s. At the duct exit, the pressure is equal to 21.7 psia. (I.) Calculate the cross-sectional flow area of the duct inlet. (II.) Estimate the temperature and velocity at the duct exit. (III.) Explain why it is (or is not) possible that the duct shape is a diverging passage. (IV.) Explain why it is (or is not) possible that the duct is a converging-diverging passage. (Hint: use quantitative reasoning and compressible flow theory for parts III and IV.)
