Air in a room at T0 = 290 K and P0 = 90 kPa is to be drawn by a vacuum pump through a 3-cm-diameter, 2-m-long adiabatic tube equipped with a converging nozzle at the inlet. The flow in the nozzle section can be approximated as isentropic. The static pressure is measured to be 87 kPa at the tube inlet and 55 kPa at the tube exit. Determine the mass flow rate of air through the duct, the air velocity at the duct exit, and the average friction factor for the duct.
The water flow rate in the pipe will be measured using the pitot tube system given in the figure. At point 1, the velocity is zero and represents the stationary point. Since there is mercury with a density of 13600 kg/m3 in the manometer and the height of the manometer is read 0.06, calculate the volumetric flow rate of the water flowing in the pipe with a diameter of 0.2 m. (ρwater = 1000 kg/m3)
