Ethane (C2H6) at 20oC and 200kPa and methane (CH4) at 45oC and 200kPa enter an adiabatic mixing chamber. The mass flow rate of ethane is 9kg/s which is twice the mass flow rate of methane .Determine the mixture temperature and pressure. Take the specific heats of C2H6=1.7662kJ/kg K, CH4=2.2537kJ/kg K.
Methane, flowing at 17.5 kmol/hr, is compressed in a steady-state adiabatic compressor (87%efficient) from 0.1013 MPa and -240°F to 0.4 MPa. What is the work required in kJ per mole ofmethane? What is the work required in kW? What is the rate of entropy generation in kJ/K hr?Use the provided diagram
There are 2 streams of oxygen is mix in a control volume. The first stream is flowing at 0.125 kg/s at 450 K and the second is flowing at 0.15 kg/s at 700 K. The product stream is leaving at 0.100 kg/s at 800 K. All processes are at atmospheric pressure.
