Take water density and kinematic viscosity as p=1000 kg/m3 and v= 1x10^-6 m^2/s. (c) water flows through an orifice plate with a loss coefficient, ko, of 10 and diameter of do= 45 mm. the flow is controlled by a gate valve downstream of the plate with a pipe diameter dy 1.5do. assuming that the total head drop across both components is δhtotal=25 m, determine the loss coefficient of the valve to maintain a flow rate through the system of 10 i/s. ignore the friction loss.

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
