PUMP SYSTEM - SYSTEM CURVE AND NPSH SUBMIT BY 8 MAY 2022 The pumping system shown below consists of a suction pipe of length 3m and diameter 80mm; delivery pipe of length 6m and diameter 80mm; 4 elbows, each with a loss coefficient of k = 0.3; total static lift = 6m; tank entry and exit loss coefficients 0.5 and 1.0, respectively; suction and delivery pipe friction factor f = 0.007Daroy. A Robuschi 150-500 pump rotates at 1470 rpm and the desired flow rate is a minimum of 200 m/h. Complete the following tasks: 1. Draw the system curve as described above on the Roubuschi pump curve data sheet supplied. Work in increments of Q 50m³/h starting at 0 (7-point curve) 2. Would you advise the client to select the 400 or 460 impeller? Give two reasons for your answer. If the 400 impeller is used: Assume: the gauge pressure in the suction tank at 115 kPa, • the vapour pressure of the water at its average operating temperature at 20C • suction height as 1.5 m. 3. Is the pump likely to cavitate?…
Q5
What’s the answer for this please ?
I need help on this question: According to the question: a) If the pipe connected to the pump inlet has a diameter of 24 mm with length (LCP) of 5 m and Darcy friction factor of 0.03, what would be the actual head rise across the pump for a case where the pump outlet pressure is 200 kPa? The difference in height between pump inlet and outlet is 0.25 m, the tank exit is sharp-edged, and the water level in the tank to the tank exit pipe (HWL) is 2 m. Also, consider that the flow velocity inside the tank is negligible. The value of the actual head rise across the pump is = ? b) What would be the pump motor power if the efficiency is 60%? The value of the pump motor power is = ?
Please solve asap.
D ¶ L The water in a large tank exits through a horizontal circular pipe of diameter D=0.01m and length L=62m. The centre of the exit of the pipe is h=1.4m 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 fp = 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
Three pipes are connected in series with properties given as: for pipe A, L= 300 m, diameter = 15 cm, for pipe B, L= 400 m, diameter= 20 cm and for pipe C, L= 600 m, diameter= 25 cm. The Manninbg's coefficient of the three pipes n= 0.011. If the total frictional losses is 5 m, excluding minor losses, determine the amount of water flowing through the pipe system.
