Hello! I'd like help with the following exercise, from Levenspiel's "Engineering Flow and Heat Exchange". Leftover air at 20ºC and 100kPa is driven by a fan through a horizontal galvanized conduit of 1 m in diameter and 10m in length at a speed of 10 m/s. What size motor should be used if its efficiency is 90% and that of the fan is 20%? I'm not sure where to start. My professor hasn't explained much about this subject.
(Q1) A small reservoir based plant is planned in a remote location to supply water into a micro turbine to generate electricity. The height of water level in reservoir is 10 m. The micro turbine is to be located at ground level at a distance of 200 m from the reservoir. To generate sufficient power, the minimum head (total head) required at the turbine inlet is 9 m with the flow rate of 0.4 m3/s. The loss coefficient (KL) at the inlet to the pipe from reservoir is calculated as 0.4. Determine the minimum diameter of the cast iron pipe (roughness, e = 0.26 mm) required for the proposed design. Take following properties of the fluid: density (EGL). 1000 kg/m3, viscosity = 0.001 kg/m-s. Draw hydraulic grade line (HGL) and energy grade line Reservoir H = 10 m Inlet, K, = 0.4 Pipe Turbine 200 m
