Consider the water pump shown in fig, Determine the power that the pump supplies to the water if the velocity of the water is at A is V= 2 m/s and the pressures at A and B are 175kPa and 350 kPa, respectively. Neglect friction losses.

Q2/: As shown in the figure, the Assumptions of the flow through the venturi is steady, incompressible, irrational with negligible frictional effects , the effect of air column on the pressure change is negligible, the pressure can be assumed to be uniform at a given cross-section of the venturi meter and the flow is horizontal . Air is flowing through a venturi meter whose diameter is 2.6 in at the entrance part (location 1) and 1.8 in at the throat (location 2). The gage pressure is measured to be 12.2 psia at the entrance and 11.8 psia at the throat. Neglecting frictional effects, take the air density to be 0.075 lbm/ft. 1.

Problem 3: Water issues from a hole in a large tank, as shown in the attached figure.Assuming frictionless flow, find L.

The flow of water from a reservoir is controlled by an L-shaped gate hinged at point A, as shown in the figure. The mass of the weight at B (a = 4 m to the right of A, b = 3 m above the base) is 5125 kg. If the gate opens when the water height is 1.75 m above the base, determine the width (in meters, not showing) of the gate.

The upper part of a water tank is divided into two sections as shown in the figure, while a fluid with an unknown density is poured on one side, the water level on the other side rises to compensate for this effect. According to the final fluid heights shown in the figure, find the density of the liquid added to the left chamber. Assume that the added liquid is immiscible with water. (ρwater=1000 kg/m3)

Water flows inside a solid cylindrical pipe, which narrows as it goes up to a height h (see diagram below). The lower horizontal section has circular cross-sectional diameter d, whereas the upper horizontal section has diameter d/2. Let us denote A to be a point at the lower horizontal section and B to be a point at the upper horizontal section. The flow speed at A and B is uд and u, respectively. The pressure at A and B is PA and PB, respectively. РА UA Oom Ja d d/21 1 UB h (a) Assuming water to be incompressible, show that the flow speed at B is four times the flow speed at A. (b) Use Bernoulli's equation to find the drop in the water pressure from A to B. Express the result in terms of h, uд, the density of water p, and the acceleration of gravity g. (c) Above certain critical height h, vapour bubbles start to appear at the top horizontal section, which hinders water flow through the pipe. Explain why this happens.

A spherical water tank with an inner radius of 11 meters has its lowest point 3 meters above the ground. Water is pumped from ground level through an inflow pipe that meets the tank at its lowest point (see figure). Neglecting the volume of the inflow pipe, how much work is required to fill the tank if it is initially empty? Use 1000 kg/m³ for the density of water and 9.8 m/s² for the acceleration due to gravity. dy 11 m (Type exact answers, using à as needed.) inflow pipe Set up the integral that gives the work (in joules) required to fill the tank. Use a vertical axis whose origin corresponds with the center of the sphere and use increasing limits of integration. 3 m
