Air at mass flow rate of 10 kg/s at 1 atm, 300 K (point1) enters an adiabatic compressor and exists at 8 atm, 600 K (point 2). Assume constant specific heat values at the average temperature.
A) Calculate the isentropic work (process 1-2s), the actual work (process 1-2), and the isentropic effiecency for the compressor.
B) Calculate the entropy generation and the irreversibility for this 1-2 process. Assume To= 300k.
air within a piston-cylinder assembly initially at 12bar 327 degree celcius undergoes an isentropic expansion to
It is known that the kinetics of recrystallization for some alloy obey the Avrami equation, and that the value of n in the exponential is 8.4. If, at some temperature, the fraction of recrystallization is .30 after 100 min, determine the rate of r..
If the filling is done rapidly, calculate the final temperature in the small cylinder, (a) assume that oxygen is an ideal gas with Cv= 5R/2 and (b) using accurate thermodynamic data for oxygen.
calculate: a) the overall train value. b) the output rational speed at shaft 5. c) the output torque at shaft 5. Relevant gear data is= NA= 17, NB= 36, NC= 19, ND= 41, worm E = double lead, worm G = triple lead, NH= 37?
