Use a well labeled block diagram to show the General structure of measurement system.
Show the input and output.
hydrogen gas is used in a carnot cycle having an efficiency of 60 with a low temperature of 300 k. during the heat
the volume of 1 kg of helium in a piston-cylinder device is initially 5m3. now the helium is compressed to 3m3 while
A double-wall heat exchanger is used to transfer heat between liquids flowing through semicircular copper tubes. Each tube has a wall thickness of t = 3 mm and an inner radius of ri = 20 mm, and good contact is maintained at the plane surfaces by ..
Discuss some of the problems that might be encountered when implementing OSHA's machine guarding standards in the workplace. Do you feel that the standards are adequate to control machine guarding hazards in general industry?
If a power plant rejects heat of 30,000,000kW/day into a nearby lake with 16,000 acre feet of water, how fast in degrees/day will the temperature of the lake rise if it is assumed that the lake is insulated and cannot reject heat in any other way?
Air is compressed by an adiabatic compressor from 95 kPa and 27°C to 600 kPa and 277°C. Assuming variable specific heats and neglecting the changes in kinetic and potential energies, determine (a) the isentropic efficiency of the compressor and (b) t..

A steel alloy contains 95.7 wt% Fe, 4.0 wt% W, and 0.3 wt% C. (a) What is the eutectoid temperature of this alloy? (b) What is the eutectoid composition?
Oxygen at 25?C and pressure of 2 bar is flowing through a rubber pipe of inside diameter 25 mm and wall thickness 2.5 mm. The diffusivity of O2 through rubber is 0.21 x 10-9 m2/s and the solubility of O2 in rubber is 3.12x10-3 kg-mole/m^-3 bar . ..
In the other stream, Refrigerant 134a enters at 14 bar, 80°C with a mass flow rate of 5 kg/min and exits as saturated liquid at 52°C. Heat transfer from the outer surface of the heat exchanger can be ignored. Determine the mass flow rate of the li..
moist air initially at 70 percent humidity and 5 c is heated to 25c. the input flow rate is 3000 cubic meters per hour
