Water flows steadily through a curved duct that turns the flow through angle = 135 degrees, as shown in Fig. 3. The cross-sectional area of the duct changes from A1 = 0.025 m2 at the inlet to A2 = 0.05 m2 at the outlet. The average velocity at the duct inlet is V1 = 6 m/s. The momentum flux correction factor may be taken as 1 = 1.01 at the duct inlet and 2 = 1.03 at the its outlet....

Your boss would like to connect a high temperature and pressure stream of steam (from another unit at the plant site) to a turbine that will be operated adiabatically and will serve as an energy source for a small electric generator. The steam is at T1 = 600 C and P1 = 10 bar. The outlet conditions of the turbine must be T2 = 400 C and P2 = 1 bar. The inlet diameter to the pipe connecting to the...
Air flows through a converging-diverging nozzle/diffuser. Assuming isentropic flow, air as an ideal gas, and constant specific heats determine the state at several locations in the system.
