Water flow through a venturi meter an inlet dia. = 100 mm and throat dia. =50 mm , P at inlet = 70 kpa. And at the throat 75 mm mercury, if the discharge coefficient = 0.95 , find the flow?

A flowrate of 3.5 ft 3/s is to be maintained in a horizontal aluminum pipe (ε = 5x10^-6 ft). The inlet and outlet pressures are 65 psi and 30 psi, respectively, and the pipe length is 500 ft. Determine the diameter of the pipe. [Answer is units of ft. ]

Q2: A flocculation tank with a discharge of 50,000 m³/day and alum dosage is 50 mg/1, Gt=4*104 at a temperature of 15 °C. This tank contains three paddles, each paddle has two boards with a dimension of 5m length, rotational speed is 2.5 rpm, and velocity gradient is 30 s¹. The distance between the center of the board and the shaft is 1.25m find: 1)Design this tank if the depth equal one-third of width, assuming depth according to design criteria of flocculation tank 2)Power required Width of the paddles?

Minor Losses A pipe system is comprised of a flush entrance, one gate valve, one 90° elbow, one 45° bend, and a globe valve. If the fluid flows at 11 ft/s, what is the head loss due to minor losses? O 12.4 ft O 14.3 ft O 22.5 ft 13.2 ft O 8.55 ft O 6.60 ft
