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?

Evaluate the challenges and opportunities in the aircraft manufacturing industry following World War II as commercial and military aircraft evolved from piston-engine to high-performance,

jet aircraft. In your analysis, consider factors that influenced the aircraft manufacturing industry with respect to designs, performance, materials, development, and production of new, high-

performance jet aircraft. Development of Alternative Actions (2 advantages and 2 disadvantages)

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.)

Water will be pumped from a reservoir free surface of which is at an elevation of “z1” to reservoir the free water surface of which is at “z2”. Both of the reservoirs’ free surfaces at atmospheric pressures.Design a piping system that transmits water from the lower reservoir to the upper reservoir at a volumetric flow rate of Q (m3 /h).

Q = 200 (m3/h) Za = 10(m) Zb= 60 (m) Zc = 75 (m) L1=200 (m) L2=125 (m) "Pipe material is "Commercial Stainless Steel" "

1) Consider necesssary fittings( valves, elbows….)

2) Given data and cost elements, determine the optimum pipe diameter of the system . In order to do this:

3) Write the energy equation between z1 and z2 by taking the major losses associated with the pipe, minor losses associated with the fittings, sudden contraction, and expansion regions inside the system and the pump total head rise ”hp” into account .

4) The average velocity of the water inside your piping system should be between 0.1 and 5 m/s. 5) Calculate the head rise “hp” that must be provided by the pump.

6) Choose a pump that provides a head rise of ”hp” (that you calculated) near its most efficient working flow rate at your given flowrate Q from the local manufacturer’s catalogues.

7) Find the cost of the pipe per one meter (TL/m) and unit electricity price ( TL/kWh). Neglect cost of the pump or pumps.

The pressure in a car tyre depends on the temperature of the in the tyre. When the air temperature is 27C, the gage pressure is 210 KPa. If the volume of the of the tyre is 0.025 m3, determine the pressure rise in the tyre when the air temperature rises to 57C. With the tyre temperature at 57C, determine the mass of air which must be bled off in order to decrease the pressure to its original value. Take the molar mass of air as 29g/mol.
