A 100 mm diameter suction pipe leading to a pump carries a discharge of 0.03m3/s of oil (0.85), if the pressure at point A in the suction pipe is a vacuum of 180mmHg, find the total energy head at point A with respect to the datum of the pump

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 liquid enters a diffuser at speed 10.8 feet/second.  The diffuser's inlet diameter is 4 inches while it's outlet diameter is 6 inches.  Determine the speed of the water at the diffuser outlet in feet/second.

In the figure below, the tank containing the water is very large and open to the air, and the pipe through which the water drains is very small. The pipe is not open to the air and the water can be treated as an ideal fluid. Find the speed at which the water is traveling in the pipe.

Question 1: Water is expelled by a jet to the environment (i.e. the water flow is surrounded by atmospheric pressure). To change the direction of the water flow, this enters to a curved pipe as show in the figure (top view perspective). Calculate the forces exerted by the flow to the pipe in x and y direction (both horizontal). Use a water density of 1000 kg/m³, Q=1 m³/s, diameter d-0.3 m. Follow the 4 steps explained in the lectures and state your assumptions clearly. 30 Question 2: Repeat question 1 but change the curvature from 30 degrees to 90 degrees. How the forces change? 90

The turbine at C draws a power P kW. If the intake B has a diameter of de mm. The pressure dg(mm) dĄ(mm) at the intake B is Ps kPa and the velocity of the water (density = 1kg/L) at that point is v (m/s).

What must the gauge pressure p be at A if the volume flow rate out of the pipe at point B is 0.0800 m^3/s?

A pipe with a diameter of 2cm is attached to a garden hose with a nozzle. If the velocity of flow in the pipe is 2ms, what is the velocity of the flow at the nozzle when it is adjusted to have a diameter of 4mm?
