Water is pumped at a rate of 24.33 m/s from tank (A) and out through a 298.05 m pipe to tank (B). The surface roughness of the pipe is 0.046 mm. When the water levels are as shown in the given figure, the head provided by the pump is 70.54 m. Calculate the pipe diameter (mm) if the water temperature is 10°C (do not assume the water mass density and the viscosity). Use f = 0.02 for the first iteration and try only one more iterations (two in total) by using Swamee and Jain formula.

Water flows at a rate of 500 gal/min through a 400-ft-long line. The first and last 100 ft of the line are 6-in-diameter cast iron pipes, while the middle 200 ft consists of two 4.24-in-diameter cast iron pipes. Find: a. Provide a diagram b. the average velocity in each section of pipe, c. the pressure drop in each length of pipe, and d. the total pressure drop.
Question 8 download image D The water in a large tank exits through a horizontal circular pipe of diameter D=0.01m and length L=94m. The centre of the exit of the pipe is h=1.0m below the water surface. We can assume that the flow entrance to the pipe is smooth so that there are no minor losses. The flow in the pipe is laminar, the friction factor can be assumed constant and can be found from h fD=64/Rep where the Reynolds number is based on the pipe diameter and mean flow speed in the pipe. Taking frictional losses into account, solve the resulting quadratic equation to calculate the speed of the flow out of the pipe. Give your answer in m/s to 2 decimal places. Use: kinematic viscosity given by v=0.00000114 m²/s density of water given by 1000 kg/m3 acceleration due to gravity of 9.81 m/s² A Moving to another question will save this response. >>
Subject: Fluid mechanic Provide complete solution.
Show complete solution and formulas used. Show the schematic diagram too. Calculate the required pipe diameter to avoid cavitation, if the pump delivers Q = 30US gallon/min water from a closed tank, where the pressure (above the water level) is p = 40kPa. The equivalent length of the smoothened concrete pipe on the suction side is 12m while the suction flange of the pump is 8m below the water level. The vapour pressure at the given water temperature is 2.8kPa. The required net positive suction head is NPSHr = 3.2m.
At point A where the diameter at of the pipe is 18 cm the pressure reading is 22.5 cm of Mercury. At point B, 3 m lower than A, the diameter is 48 cm and the pressure reading is 50 cm of Mercury. If the total head loss between the two points is 1.50 m, solve for the discharge. Water is flowing through the pipe. subject: hydraulics
