Question 3 (5 points) For the reservoir at the top of the figure: a) Determine the hydrostatic force and location of the center of pressure on the chamfer (diagonal face) at the left end if it is 15 feet wide (the dimension into and out of the screen/page), and determine the wall can safely support the force if its maximum load is 3500 pounds per square foot. b) Determine whether a hollow concrete block of 5' X 6' X 10' with a total weight of 9500 pounds will float in the reservoir and, if so, how much of the block will remain above the water surface. (Consider the likely orientation of the block in the water.)

The following steel siphon (L constant elevation difference of 20 m. The distance between reservoir A and siphon summit S is 100 m.500 m, D 200 mm) connects two reservoirs with a a) Assume f= 0.020 and calculate steady state flow rate between the two reservoirs b) Calculate pressure head at the summit Identify on the figure the region of the system under sub atmospheric pressure

Excess irrigation water runs off a farmer's field and carries fertilizer and other pollutants. The field has the following characteristics: flow =mg/L. it combines with a hog pen washout stream with a flow of 5 m³/min and TSSof 800 mg/L. what is the TSS content of the combined stream in mg/L?= 20 m³/min, TSS = 400

1. A sample of saturated clay was placed in a container and weighed. The weight was 6 N. The clay in its container was placed in an oven for 24 hours at 105°C. The weight reduced to a constant value of 5 N. The weight of the container is 1 N. If Gs = 2.7, please determine the (a) water content. (b) void ratio, (c) bulk unit weight, (d) dry unit weight, and (e) effective unit weight.

2. 1 cfs of water (T= 95°F) is carried by a 3-in diameter cast iron pipe a) Determine friction factor b) Show quantitatively whether flow is laminar or turbulent

A double acting cylinder has a bore of 92 mm. The rod diameter is 35 mm. It must produce a pushing force of 18.8 KN. The flow rate available in both directions is 0.01 m3/min. Note: Number are randomly generated. it is possible to get some huge dimensions. Do not write the units, provide the answers in the requested units. Calculate the system pressure needed. Express your result In Pa. (Round the answer, no decimal is required Example 123.2 becomes 123, 123.6becomes 124) The force with which it pulls, given the same pressure. Express your result In N. (Round the answer, no decimal is required Example 123.2becomes 123, 123.6 becomes 124) The speed on the outstroke. Express your result Inm/s. (Round the answer to 4 decimal Example1.21212 becomes 1.2121) The speed on the instroke. Express your result Inm/s. (Round the answer to 4 decimal Example1.21212 becomes 1.2121) The power used on the outstroke. Express your result In watts. (Round the answer, no decimal is required Example 123.2 becomes 123, 123.6 becomes 124) The stroke of the actuator S knowing that it takes1.82 s for the piston to travel back and forth. (Round the answer to 4 decimal Example 1.21212becomes 1.2121)

Water @ 80°F flows from a storage tank through a horizontal, 80-ft long, 4-in diameter galvanized iron pipe that includes a flow control valve. a) Ignore minor losses and calculate depth of water in the tank above the discharge pipe to convey 2 cfs. Use Darcy equation for friction head loss. b) Repeat calculation using Hazen-Williams equation for friction head loss c) List 2 reasons that water hammers could develop in this pipe and list 2 mitigations to either eliminate or reduce the potential for water hammers.

10.1 On a distant planet small-amplitude waves travel across a1-m-deep pond with a speed of 5 m/s. Determine the acceleration of gravity on the surface of that planet. 10.2 The flowrate per unit width in a wide channel is q2.3 m²/s. Is the flow subcritical or supercritical if the depth is(a) 0.2 m, (b) 0.8 m, or (c) 2.5 m? 10.3 A rectangular channel 3 m wide carries 10 m³/s at a depth of2 m. Is the flow subcritical or supercritical? For the same flowrate,what depth will give critical flow?

Question [3] Freshwater and seawater flowing in parallel horizontal pipelines are connected to each other by a double U-tube manometer, as shown in the figure below. Pmercury = 13600 kg/m³ - Pfreshwater = 1000 kg/m³ - Pseawater = 1035 kg/m³ - Pair = 1.2 kg/m³ a) Determine the pressure difference between the two pipelines. [25 points] b) Can the air column be ignored in the analysis?
