How can I find the input power required without a 6 degree conical expansion added to the exit? in horse power A 86% efficient pump delivers water at 20°C from one reservoir to another20 ft higher as shown in the figure below. The piping system consists of 60ft of galvanized-iron 2-in pipe, a reentrant entrance, two screwed 90° long-radius elbows, a screwed-open gate valve, and a sharp exit. The flow rate is0.4 ft³/s. For water at 20°C, take p = 1.94 slug/ft³ and μ = 2.09E-5 slug/ft.s.For galvanized iron, ε = 0.0005 ft. For the given flow, take Kreentrant1.0, Kelbows = 2(0.41), Kgate valve ≈ 0.16, and Ksharp exit ≈ 1.0. Take πT =22/7. For the given flow take f≈ 0.0266.20 ftPump6° cone

Water is to be pumped (whose characteristics below) from one large open tank into an apparatus working under a pressure of 2 atm. The pipe diameter is 0.15 m and the pipe length is 61 m. There are minor losses at the entrance, exit and throughout the pipe. The friction factor will be taken as 0.02. JEfficiency of the pump =0.7 Calculate: The flow-rate and shaft-power needed when the pump is operated at 1000 rev/min. The flow rate and the power when the speed of the pump increased by 10%. c) The flow rate and the power when two pump operate at parallel.
A new pump is required for the water supply system of a high-rise office building. The system requires 0.06 m³/s of water pumped to a reservoir at the top of the tower 340 m above the street. City water pressure at the street-level pump inlet is 400 kPa gage. The piping is to be commercial steel, the overall length is 20 percent greater than the tower height, and there are fittings every 10 m with loss coefficients of 0.2. Determine the minimum diameter required to keep the average water velocity below 3.5 m/s in the pipe. Calculate the pressure rise required across the pump and estimate the minimum power needed to drive the pump.

A centrifugal pump pumps water at a flow rate of 7 m³/s to a height of 10 m. If the pump works at the best efficiency point, find the pump impeller diameter, pump speed, the best efficiency value of the pump, the head at the best efficiency value, and the specific speed of the pump, given that CQ=0.15 CH=6 CP=0.75.
(a) A pump draws water (50°F) from a reservoir, where the water-surface elevation is 520 ft and forces the water through a pipe 5000 ft long and 1 ft in diameter. This pipe then discharges the water into a reservoir with water-surface elevation of 620 ft. The flow rate is 7.85 ft/s and the head loss in the pipe is given by hi = 0.01 where, Land D is the length and diameter of the pipe respectively; Vis the velocity. Determine the head supplied by the pump and the power supplied to the flow. Also draw the Hydraulic Gradient Line (HGL) and Energy Gradient Line (EGL) for the system. Assume that the pipe is horizontal and is 510 ft in elevation. Given, viscosity of water at 50°F is 62.4 lbf/ft'.
