Air flows down a pipe with a diameter of 0.15 m. At the inlet to the pipe, the Mach number is 0.25, the pressure is 70 kPa, and the temperature is 35°C. If the flow can be assumed to be adiabatic and if the mean friction factor is 0.005, determine the length of the pipe if the Mach number at the exit is 0.6. Also, find the pressure and temperature at the exit to the pipe.

Air flows through a constant area duct. The pressure and temperature of the air at the inlet to the duct are P1 = 100 kPa absolute, and T1 = 298 K, respectively. Inlet Mach number is M1 = 0.1. Heat is transferred to the air as it flows through the duct and as a result the Mach number at the exit increases. a) Find the pressure and temperature at the exit, while the exit Mach number changes between M=0.2 to...
Water flows steadily downwards through a circular pipe of internal diameter 0.15 m inclined at 30° to the horizontal. A U-tube manometer is used to determine the pressure difference between two points displaced axially along the pipe by a distance 1.25 m.
