A reservoir at 300 ft elevation has a 6-in.-diameter discharge pipe located 50 ft below the surface. The pipe is 600 ft long and drops in elevation to 150 ft where the flow discharges to the atmosphere. The pipe is made of riveted steel with a roughness height of 0.005 ft. Determine (a) the flow rate without a head loss and (b) the flow rate with the pipe friction head loss. Since the velocity is not known for part b and the Reynolds number and friction factor depend on velocity, you will need to iterate to find the solution. A good first guess is the velocity from part (a).

Two pipes are connected in series with a diameter ratio of 2:5. If the flow velocity in the smaller diameter pipe is 12 m/s, determine the head loss due to: a. sudden contraction, b. sudden enlargement.

A 250 mm diameter and 3 km long straight pipe connects two reservoirs of water surface elevations 135.00 m and 60.00 m. A 1.5 km long, 300 mm diameter pipe is laid parallel to 250 mm diameter pipe from its mid-point to the lower reservoir. Neglecting minor losses and assuming friction factor as 0.02 for both the pipes. Find the original discharge and the increased discharge

A centrifugal pump was purchased to pump the water from an open tank to a water jet spray cleaner. The spray cleaner requires a pressure of 75 kN/m2 (gauge pressure). The hose that connects the tank to the pump and to the spray jet is 25 m long and has an internal diameter of ¼ inch (0.64 cm). The hose also has a small “kink” in the line that adds some extra head loss with an approximate head loss coefficient of Kkink = 0.3. The spray jet nozzle is located 15 m above the tank liquid surface. Assuming a frictional loss of 0.002 in the line, determine the flow rate and head of the pump. Assume that the spray nozzle has the same diameter as that of the hose and α=1. The centrifugal pump was tested by the supplier before delivery and the performance data is provided in the table below.

Water at 80°F flows from a storage tank through 618 ft of 6-in Schedule 40 steel pipe, as shown in the figure. Taking the energy loss due to friction into account, calculate the required head hin feet above the pipe inlet to produce a volume flow rate of 1.65 ft³/s. (round the final answer to three significant figures) h 6-in Schedule 40 steel pipe pipe length

Water flows from the nozzle attached to the spray tank shown in the figure below. Determine the flowrate if the loss coefficient for the nozzle (based on upstream conditions) is 0.75 and the friction factor for the rough hose is 0.11. Assume p₁ = 150 kPa, z₁ = 0.5 m. Q= -P₁ m³/s 40° Nozzle diameter = 7.5 mm D = 15 mm € = 1.9 m

Problem: A pump draws water through a 300-mm diameter cast iron pipe, 15 m long from a reservoir in which the water surface is 4.5 m higher than the pump and discharges through a 250-mm diameter cast iron, 75 m long, to an elevated tank in which the water surface is 60 m higher than the pump. Considering f = 0.02 and the coefficients for minor head losses (kentrance = 0.5, kpend = 0.35, and kexit = 0.5), compute the following: a. Pressure head at the suction side of the pump b. Pressure head at the discharge side of the pump c.
