12. Points A and B are 3000 ft apart along a 10-in. new steel pipe. B is 220 ft higher than A. With a flow of 3.2 efs of water from A to B, what pressure must be maintained at A if the pressure at B is to be 50 Ib per sq in.? Answer should be: 164 lb per sq. inch Show your handwritten solution.
1- Derive an expression for the flow rate q over the spillway shown in figure bellow per foot of spillway perpendicular to the sketch. Assume that the sheet of water is relatively thick, so that surface -tension effects are negligible. Assume also that gravity effects predominate so strongly over viscosity that we can neglect viscosity. H.

a) Two pipes have a length ? each. One of them has a diameter D, and the other a diameter d.if the pipes are arranged in parallel, the loss of head when a total quantity of water Q flows through them is h, but, if the pipes are arranged in series and the same quantity Q flows through them, the loss of head is H. If ?=?/2, find the ratio of H to h, neglecting secondary losses and assuming the pipe coefficient f has a constant value. b) A pipeline of 0.6m diameter is 1.5km long.To increase the discharge, another line of the same diameter is introduced parallel to the first in the second half of the length.Neglecting minor losses, find the increase in discharge if 4f = 0.04. The head at inlet is 300mm. c) Determine the difference in the elevations between the water surfaces in the two tanks which are connected by a horizontal pipe of diameter 300 mm and a length of 400 mm. The rate of flow of water through the pipe is 300 litres/s. Consider all losses and takef=0.008. d) Water at 20°C is…

Q2\ The diagram shows a tank draining into another lower tank through a pipe, both tanks are open. Calculate the velocity, using the data given on the diagram. k = 0.5 20 m k = 1 50 mm bore, 50 m long f = 0.007
Problem 3. Performance data for a pump are given in the table below. From a curve fit to the data, the pump curve is given by H₂ = H0 - C₂ Q² where H₁ = 180 ft and C₂ = 1.524 × 10-5 ft/gpm². This pump is used to move water at STP between two open reservoirs with an elevation increase of Az = 50 ft through a commercial steel pipe of length L = 1200 ft and diameter D = 1.0 ft that contains two 90° elbows (equivalent length of 30 diameters) and an open gate valve (equivalent length of 8 diameters). The flow entrance and exit for the reservoirs are abrupt. (a) Plot the pump curve and system curve on the same figure. (b) Calculate the flowrate with the gate valve open. (c) Calculate the equivalent length for the gate valve in order to reduce the flowrate by half. NOTE: Your calculations for this problem will require iteration because the friction factor for this case does depend on Q. Thus, it is recommended you use either EES (see solution for Example 19 from lecture) or Excel to get…
Question 3 Consider 2 which shows a pipe system connecting two reservoirs. The pipe diameter changes at point B as shown in the image A 10 cm 23 m NOT TO SCALE Figure 2: 9 m 6 cm с 3 m 1. Describe what is referred to by the hydraulic gradient line and the energy gradient line. What is the difference between the two levels? In what scenario will the energy and hydraulic grade lines coincide? 2. Calculate the velocities in the two segments of the pipe. Take into account the friction losses through the pipe, entry loss to the pipe and the shock contraction losses at B. Take the pipe friction factor as 0.005 and the coefficient of contraction at B as 0.6. 3. Draw the energy gradient line and the hydraulic gradient line for the system.
Please give detailed explanations and show your work clearly - I will be using this to study for an upcoming exam. Please do as much as you can but don't worry if you cannot complete the entire problem. Thank you!
