A single stage reciprocating compressor takes 1 m3 of air per minute at 1.013 bar and 15°C and delivers it at 7 bar. Assuming that the law of compression ispv1.35=c , and that clearance volume is negligible, calculate the indicated power.
how to draw water and oil projection which there are 2 containers and have hole at the same level?
a venturimeter is used to measure liquid flow rate of 7.5x103L/min. the difference in pressure across the venturimeter is 8m of the flowing fluid. the pipe diameter is 0.19m. determine the throat diameter of the venturimeter. given Cd value is 0.96
how much heat would be required to transform 2 kg of saturated liquid-vapor mixture of water at 60% quality and 80 degree celcius to saturated vapour at constant pressure and then to steam at 150 degree celcius and 0.2 MPa at constant volume?
Steam enters with negligible velocity a well-insulated turbine operating at
steady state at 4 MPa, 320°C. The steam expands to an exit pressure of 0.07
MPa, a quality (dryness fraction) of 0.95 and a velocity of 90 m/s. The diameter
of the exit is 0.6 m. Neglecting potential energy effects, find the power
developed by the turbine in kW
In a gas turbine unit air is drawn in at 1.02 bar and 15°C, and is compressed to 6.12 bar. Calculate the thermal efficiency and the work ratio of the ideal constant pressure cycle, when the maximum cycle temperature is 800°C.
The relative molecular mass of carbondioxide CO2 is 44. In an experiment, the value of γ for CO2 was found to be 1.3. Assuming that CO2 is a perfect gas, calculate the specific gas constant R and the specific heats at constant pressure cp and at constant volume, cv
A quantity of a certain perfect gas is compressed from an initial state of 0.085m3, 1 bar to a final state of 0.034m3, 3.9 bar. The specific heat at constant volume is 0.724 kJ/kg K and the specific heat at constant pressure is 1.02 kJ/kg K. The observed temperature rise is 146 K. Calculate the gas constant R, the mass of gas present, and the increase in internal energy.
A vessel of volume 0.2m3 contains nitrogen at 1.013 bar and 15°C. If 0.2 kg of nitrogen is now pumped into the vessel, calculate the new pressure when the vessel has returned to its initial temperature. The molar mass of nitrogen is 28 kg/K - mol and it may be assumed to be a perfect gas.
