8-C) As shown below water is pumped and sprayed through a nozzle into the atmosphere at 20 m/s at an elevation 10 m above the reservoir surface. The mass flow rate is 40 kg/s and the volumetric flow rate is 0.040 m3/s. The large diameter inlet pipe total length is 50 m. The pump effidency is 65%. The longer smaller diameter pipe leaving the pump is 200 m in total length. The pipes have different diameters as indicated below. The...

7.8 A horizontal pipeline consists of a 38 mm diameter pipe, 6 m long in total. The pipe has 2 bends, each with a loss coefficient k 2,2, as well as a filter and a valve with length to diameter ratio of 120 and 65 respectively. Water flows at a rate of 5 L/s through the system. Take the friction factor as f 0,002 and determine (a) The equivalent length of each bend, the filter and the valve. (10,45 m,...

Air flows at 30 ° C at a uniform speed of 23 m / s along a smooth flat plate. Calculate the approximate location x along the plate where the boundary layer is likely to be completely turbulent. Air density and viscosity at T = 30 °C are 1.164 kg / m3 and 1.872 x 10-5 kg / m, respectively. The critical Reynolds number is 100,000 and the turbulent flow begins at 30 times the critical Reynolds number. 20:19 small...
