A3-ft-diameter duct is used to carry ventilating air into a vehicular tunnel at a rate of 9000 ft3/min. tests show that the pressure drop is 1.5 in. of water per 1500 ft of duct. what is the value of the friction factor for this duct and the approximate size of the equivalent roughness of the surface of the duct? ans: f = 0.0292, e = 0.0132ft.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
