How to solve this question?
- Write down the steady flow energy equation for an open systemcontrol volume. Stating any assumptions you have made, apply thisequation to
- A steam boiler
- A nozzle

- Carbon dioxide enters a compressor with a mass flow rate of 0.5kg/s. The compressor inlet pressure is 1 bar (absolute) and theinlet temperature is 300K. The outlet pressure is 6 bar (absolute)and the outlet temperature is 450K.
- Calculate the density of the carbon dioxide at the compressorinlet.
- Calculate the volume flow rate through the compressor.
- If a heat loss of 25 kJ/kg occurs during the compressionprocess, and the specific internal energy of the carbon dioxideincreases by 110 kJ/kg, calculate the input power to thecompressor. [You may assume that all kinetic and potential energyeffects are negligible]
Take specific gasconstant for carbon dioxide R = 0.189 kJ/kg K
