Energy Loss in Bends and Fittings a) What is the difference between major loss and minor losses in a pipe network? Give at least three examples of minor losses? b) The following information has been collected in the lab during "Head Loss in Bends and Fittings" experiment: Manometer readings for sections before and after a bend: h₁=326 mm and h₂=253 mm Q=0.28 lit/s Pipe diameter 1.83 cm Calculate the head loss coefficient (K) for this bend. - c) Name the fitting from the lab experiment (excluding the valve) that should have the highest head loss and explain why this is the case?
The diagram below shows a pumping system to pump water to an elevated tank. The next page shows the performance curve of a specific type of centrifugal pump. The loss factors at the inlet and outlet are 0.5 and 1.5 respectively while the loss factor associated with the bend is 1.5. The diameter of the pipe is 0.050 m while the total pipe length is 400 m. In order to simplify the calculation you can assume that the friction factor is f= 0.036. Determine the duty point of this pumping system and thus determine the flow rate of the pump for an impeller diameter of 140 mm? Also determine the shaft power of the pump and give an estimate of the pumps efficiency at the duty point. Given that the pump is located 1.80 m above the water surface (1), and the pipe length from inlet to pump is 6.0 m, determine the NPSHA at the pump and state whether cavitation is likely to occur.
