Problem 14.2 A jet of water (r = 1000 kg/m³) is deflected by a vane mounted on a cart. The water jet has a constant cross-sectional area, A = 50 cm², which is projected off the vane at an angle q = 30° with respect to the horizontal. The pressure everywhere within the jet is atmospheric. The incoming jet velocity (with respect to the ground) is Vjet = 4.5 m/s. The cart has mass 50kg. Determine: a. the forces, Fx and Fy required to hold the cart stationary Vjet Vcart Fy Fx b. the horizontal force component, Fx, if the cart moves to the right at the constant velocity, Vcart = 3 m/s c. the horizontal acceleration of the cart at the instant when the cart moves with velocity Vcart = 2.5 m/s if no horizontal forces are applied Ans: a) 10 N

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. >>
