A fire starts in an apartment building in downtown Boston. When the firefighters arrive, they immediately get to work putting out the fire using a fire hose. The water for the fire hose is provided by a fire hydrant at ground level. Assume that the velocity of the liquid coming from the fire hydrant is 1.6 m/s, and that the pressure at the hose nozzle is atmospheric pressure (101000 Pa). a. The firefighters start with the ground floor, so there is no change in height between the fire hydrant and the hose nozzle. If the velocity of the water coming out of the nozzle is 12.8 m/s, find the pressure at the fire hydrant in units of Pa. b. After the ground floor fire is put out, another fire is spotted on another floor. A firefighter carrying the hose is lifted on a platform to the same height as the fire, which is 44.35 m above the ground. Assuming that the pressure found in part a) remains constant, what would be the new velocity of the water coming out of the nozzle at this new height?

A pumping station wet well operates between 540- and 550-ft elevation. The pump curve is deϐined by the following points: 80 ft at zero ϐlow, 78 ft at 200 gpm, 65 ft at 800 gpm, and 50 ft at 1200 gpm. The pump discharge contains an equivalent of 50 ft of 6-in. pipe. The discharge pipe is 120-ft long and terminates at a splitter box, elevation 570. Using C=100, plot the pump curve and the corrected pump curve. Plot the pump discharge curves at each wet well elevation and for C=100 and C=140. What is the pump ϐlow at the low and high wet well elevations for newand old pipe?
Q(in) is a constant inflow which maintains the water level in the tank. Find the horizontal force needed to hold the tank stationary. If you could make any notes on steps in the method to make it clearer that would be great too. Thanks in advance!
Complete Solution please, thanks. 3. A vertical circular stack 30 m high converges uniformly from a diameter of 6 m at the bottom and 4.5 m at the top. Gas with a unit weight of 0.12 N per cubic meter enters the bottom of the tank with a uniform velocity of-assume values with decimals between 3 to 4 m per second- enters the stack. The unit weight increases by 7.5 percent every 2 meters. Find the velocity of flow at every 5 meters along the stack.
Problem 3: Water issues from a hole in a large tank, as shown in the attached figure.Assuming frictionless flow, find L.
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.
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
A storm drain has a maximum capacity of 120 L/min. During heavy rains, an influx of 240 L/min approaches the drain. Assuming the drain is cylindrical, by how much would the drain radius need to be increased to handle the heavier rainfall? Assume the water travels at the same linear speed in both drains.
