Dry air is contained in a tank with fixed volume at 200 degrees Celsius and a pressure of 5 bar. Then the fluid is heated so that its temperature reaches up to 300 degrees Celsius. If the volume of the tank is 0.2 m^3, find the transferred heat and final pressure and the change in entropy.
Air enters a 0.6 m diameter fan at 16 deg C, 101 kPa, and is discharged at 18 deg C, 105 kPa, with a volumetric flow rate of 0.35 m^3/s.
for a 3 sigma control chart what is the probability of four successive points plotting outside 2 sigma limits? if such
Containers arrive at a stocking station on a conveyor at the rate of five per minute. Container weight is 25 kg. Conveyor height is 50 inches and the stocking point is 70 inches above the ground. The stocking operation involves a twisting motion.
a smaller power plant produces steam at 3 mpa 600 c in the boiler. it keeps the condenser at 45 c by transfer of 10 mw
water in a piston-cylinder initially starts at t 400of and p 200 psia. the piston is heated until it final volume is
a temperature control device is to be made from a rectangular copper strip with a cross-section 4 mm times 8 mm which
a countercurrent heat exchanger is being used to heat a liquid food from 15 to 17 c . the heat exchanger has a 23mm
A steam power plant operates on the ideal reheat Rankine cycle. Steam enters the high pressure turbine at 6 MPa and 4000C and leaves at 2 MPa. Steam is then reheated at constant pressure to 4000C before it expands to 20 kPa in the low pressure turbin..
Air enters a non-ideal gas turbine at T1 = 2290°F, P1 = 196 psia and exits at T2 = 1200°F, P2 = 14 psia. (a) Assuming constant specific heats evaluated at 1000F, find the turbine efficiency using the Air Tables.
