Air is flowing at steady state through a 5 cm diameter pipe at a flow rate of 0.35 mole/min at P = 5 bar and T = 500 K. It flows through a throttle valve and exits at 1 bar. Assume air is an ideal gas with CP = 29.1 J/mol-K. If the throttle valve was…

A common problem in the design of chemical processes is the steady-state compression of gases from a low pressure P1 to a much higher pressure P2. We can gain some insight about optimal design of this process by considering adiabatic reversible compression of ideal gases with stage-wise intercooling. If the compression is to be done in…

Steam is fed to an adiabatic turbine at 4 MPa and 500°C. It exits at 0.1 MPa. (a) If the turbine is reversible, how much work is produced per kg of steam? (b) If the turbine is 80% efficient, how much work is produced per kg of steam? . Methane is compressed in a steady-state…

Propane is to be compressed from 0.4 MPa and 360 K to 4 MPa using a two-stage compressor. An interstage cooler returns the temperature of the propane to 360 K before it enters the second compressor. The intermediate pressure is 1.2 MPa. Both adiabatic compressors have a compressor efficiency of 80%. (a) What is the…

Liquid nitrogen is useful for medical purposes and for research laboratories. Determine the minimum shaft work needed to liquefy nitrogen initially at 298 K and 0.1013 MPa and ending with saturated liquid at the normal boiling point, 77.4 K and 0.1013 MPa. The heat of vaporization at the normal boiling point is 5.577 kJ/mol, and…

        Question 1: Suppose that graduating from a university only serves as a signal of high ability (and is not useful in any other way) and that only high-ability individuals can graduate from university. The costs of a university education are denoted by c. Furthermore, the productivity of low-ability workers is £20,000…
