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.
