air behaves as an ideal gas with R = 0.287 k J k g K.

A compressor operates at steady state and takes in air from ambient 0 kPa, gage and 300 K. The outlet pressure is 60 kPa, gage and 300 K. Determine:
1. the mass flow rate if the inlet area is 10 cm² and the inlet pressure is -3 kPa, gage.
2. the minimum outlet temperature that is possible for this compressor.
3. the isentropic efficiency of the compressor, assuming no heat loss.
4. if there is a heat loss of 20 kJ/kg, the work required to run the compressor, and the new isentropic efficiency.

outlet is 500K

For these problems, assume air behaves as an ideal gas with R=0.287kJkgK. A compressor operates at steady state and takes in air from ambient 0 kPa, gage and 200 K. The outlet pressure is 60 kPa, gage and 400 K. Determine: the mass flow rate if the inlet area is 20 cm2 and the inlet pressure is -5 kPa, gage. the minimum outlet temperature that is possible for this compressor. the isentropic efficiency of the compressor, assuming no heat loss....

A mass of m = 1 Kg of an ideal gas (gas constant R= 278 J/KgK) undergoes two polytropic processes. During the first process temperature increases from 27 0C to 237 0C and volume decreases from 1 m3 to 0.3 m3. During the second process temperature increases to 473 0C and volume is constant. The isentropic exponent of the gas is 1.4. Determine (a) Polytropic exponents (b) missing properties of the gas (c) heat and work of the first process...

1) A gas turbine operates on an ideal Joule cycle using air (γ = 1.4; R = 0.287 kJ/kg K) as working fluid. Air enters the compressor at temperature of 27◦C and pressure of 1.25 bar and is compressed to 7.6 bar. When the maximum cycle temperature is limited to 800 oC, calculate, (i) the thermal efficiency and work ratio of the cycle (ii) the temperature of air exiting the turbine and the change in specific entropy of turbine process...

The volume of some air, assumed to be an ideal gas, in the cylinder of a car engine is 540cm^3 at a pressure of 1.1 x 10^5 Pa and a Temperature of 27 Degree celsius. The air is suddenly compressed, so that no thermal energy enters or leaves the gas, to a volume of 30cm^3. The pressure rises to 6.5 x 10^6 Pa. Determine the Temperature of the gas after compression.

A 25-L sample of an ideal gas with ? = 1.67 is at 250 K and 50 kPa. The gas is compressed adiabatically until its pressure triples, then cooled at constant volume back to 250 K, and finally allowed to expand isothermally to its original state. a. Sketch this cyclical process in a pV diagram (the sketch should be drawn to scale and labelled). b. How much work is done on the gas? c. For each step in the process...

A monatomic ideal gas has an initial temperature of 381 K. This gas expands and does the same amount of work whether the expansion is adiabatic or isothermal. When the expansion is adiabatic, the final temperature of the gas is 290 K. What is the ratio of the final to the initial volume when the expansion is isothermal?
