Air is taken from the atmosphere (20 °C and 101 kPa) through a converging nozzle and guided through a long insulated tube of 20 mm diameter and constant area. The flow in the nozzle is isentropic. The machine number at the inlet of the constant area tube is 0.15. Evaluate the relationship of mass flow through the tube. Calculate T* and P* for the isentropic process. Calculate T* and P* for the flow through the constant area tube show the static and stagnation state points. corresponding in a Ts diagram.
