2. Water is pumped from a lower reservoir using a 75 kW pump. If the height of water at the higher reservoir is 120m. And the flow rate of the pump is 0.03 m^3/s, what are the head losses of the system? 0.03 m's 120m 75kW Pump
A horizontal water pipeline 50-cm diameter carries a discharge of 0.5 m/s at a pressure of 55 kN/m?. It then reduces to 300-mm diameter. For the 300-mm pipe, calculate the (a) velocity (m/s) and (b) pressure head (m).
Three reservoirs A, B and C at water levels of 25 m, 12 m and 8 m are connected by a pipe network. 1200 m length pipe of diameter 0.5 m and f = 0.013 draws water from A. 1000 m length pipe of diameter 0.4 m and f = 0.015 draws water from B and joins the pipe end from A. The reservoir C is connected to this junction by 900 m length of pipe 0.6 m diameter with f = 0.011 What would be the direction of flow? * Reservoir A feeds reservoirs B and C. Reservoir B and C feed reservoir A. Reservoir A and B feed reservoir C. Reservoir C feeds reservoirs A and B. If the flow in the 900m pipe is 0.60 m^3/s, what would be the flow in the 1000m pipe? 0.064 0.042 1 0.129 0.091 Back Next Clear form
Three reservoir, named A,B, and C are connected by Pipe 1, Pipe 2, and Pipe 3 respectively joining at a common junction. Determine the into or out of the reservoir A in the pipe system, given the following data. Use n=0.011 for all pipes. Reservoir A at El. 30 m, B at El. 24 m, and C at El. 15 m Pipe 1: 30 cm dia. 1200 m long Pipe 2: 20 cm dia. 900 m long Pipe 3: 16 cm dia. 1500 m long
A new 45 cm CI pipe, 600 m long carries 260 L/s of water from an upper reservoir A, and flows into two new cast-iron pipes each 500 m long connected to two lower reservoirs. One pipe is 30 cm in diameter that leads to reservoir B, with water surface 5.0 lpwer than that in A. If the water surface in the third reservoir C is 2.0 m lpwer than that in B, what is the size of the pipe leading to C. Use Manning's n= 0.011.Neglect minor losses.
M - Problem 3: For these three reservoirs please assume that the elevations of the waterlines in reservoirs 1-3 are: h, 30 m, h₂-20 m, and h, 10 m. Also, please assume that the lengths of pipes 1-3 are L₁ 1000 m, L₂ 2000 m, and L3 = 3000 m; the diameters of all three pipes are D₁ D₂ D₂ = 2.0 m; and the friction coefficients of all three pipes are f f₂=fa=0.015. If you estimate that the total head at Junction "J" is H, = 22 m please: 1) calculate the resulting net volumetric flow rate into junction "J" and 2) determine if the actual total head at junction "J" is above or below H, = 22 m. h₂ Reservoir 1 h₂ 7 Reservoir 2 Pipe D Reservoir 3 ha Pipe 3 Pipe 2 a
