A certain part of stainless-steelpiping of a water distribution system involves a parallel section.Both parallel pipes have a diameter of 30 cm. One of the branches (pipe A) is 1500 m long while the other branch (pipe B) is 2500 m long. If the flow rate through pipe A is 0.4 and 0.31 m3/s, respectively. Pipe A has a half-way-closed gate valve (KL= 3)while pipe B has a fully open globe valve (KL= 9), and the other minor losses are negligible. Determine the mechanical power of pump for the sy

Hot oil is pumped through a heat exchanger (see figure below) at a flow rate of 0.5 L/s. An inlet manifold equally distributes the oil into 20 parallel, 5-mm-diameter copper tubes that are about 1 m in length. The oil cools down as it flows through the copper tubes. Oil then exits through an outlet manifold. The viscosity of the oil is 250 centipoise and its density is 950 kg/(m^3). Assuming uniform pressure in the manifolds and laminar flow through the tubes. calculate the total head loss (in meters) across those 20 copper tubes. COPPER TUBES MANIFOLDS Round your answer to 2 decimal places.

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

Water flows through a pipe 5cm in diameter and 32m long between two tanks with a square-edged non-projecting entrance and exit. The flow rate is controlled by a gate valve which when fully open has a loss factor of 0.23. What is the height difference between the tanks if the volume flow rate is 4.2 x10-3 m^3/s? For laminar flow f=16/Re For turbulent flow f=0.08/Re^0.25 Density of water, rho, is 1000 kg/m^3, viscosity of water, mu , is 0.001Pa.s.
