2. A 6 in. pipe, as shown in the figure, takes water from a reservoir and terminates in a nozzle havinga jet diameter of 2 in. Assuming a nozzle loss of 8 percent of the velocity head in the jet, computethe discharge (in SI units). Also, make a table showing the elevation head, velocity head, pressurehead, and total head at each of the six stations. Lastly, draw the hydraulic gradient line (H.G.L.) &the energy gradient line (E.G.L.).Head losses in pipe:1 to 2:3.00 m2 to 3:9.00 m3 to 4:4 to 5:18.00 m6.00 m1W.S.ELEV. 140ELEV. 128 MELEV. 15M5 6

4. The system in Fig. consists of 1200 m (length) of 0.05 m (diameter) cast iron pipe, two 45° long-radius elbows, four 90° flanged long-radius elbows, and a fully open globe valve. If the elevation at point 1 is 400 m, what gage pressure is required at point 1 to deliver 0.005 m³/s of water at 20°C into the reservoir? Average surface roughness of cast iron is ε = 0.26 mm. For water at 20°C, take density, p = 998 kg/m³; dynamic viscosity, μ = 0.001 Pa-s; and acceleration due to gravity, g = 9.81 m/s². 90° elbow: KL90, elbow K₁ = 0.5 ent Elevation (1 400 m = 0.3 45° elbow: KL45,elbow=0.2 Elevation 500 m !

For the flow configuration shown, you are required to design a pump station to transfer water from the bottom tank to the upper tank. In your own words, explain the steps that are needed to be followed for the design of the pump system. Your answer should be typed and not more than one page. The pipe equivalent roughness is 1.5 mm. And a valve with a k=10 is located just upstream of the lower reservoir (other losses are negligible). Take p=1000 kg/m”, g = 9.81 m/s?, and u = 1.179 x 102 kg/m.s.
Water is pumped between two reservoirs in a pipeline with the following characteristics; (d=275mm, L= 50m, = 0.02, minor loss is neglected. The pump performance curve is approximated by the equation: H,=21.5-6507 Where H, is in meters and Q is in m/s. Determine the discharge O and pump head /7 when two pumps in series are used for total static head (4Z=25m).

An air-conditioning system is designed to have a ductwith a rectangular cross section 1 ft by 2 ft, as shown. Duringconstruction, a truck driver backed into the duct and made it atrapezoidal section, as shown. The contractor, behind schedule,installed it anyway. For the same pressure drop along the pipe,what will be the ratio of the velocity in the trapezoidal duct tothat in the rectangular duct? Assume the Darcy-Weisbach resistance coefficient is the same for both ducts.
