Find the average velocity of the water leaving the tank.

Answer to Problem 36P
The average velocity of the leaving water in the tank is
Explanation of Solution
Given data:
Refer to the Figure Problem 8.36 in the textbook, which shows the tank is filled by water using pipes 1 and 2.
The water level increases in the rate of 0.1 in/s.
The diameter of the tank is
Formula used:
Write the expression for the volume flow rate.
Here,
Calculation:
Consider that the constant water density.
From the Figure Problem 8.35 in the textbook, write the volume flow rate expression for inlet and outlet volumetric flow rate expressions.
Re-arrange the equation,
Refer to the Figure Problem 8.35 in the textbook, substitute
Reduce the equation as follows,
The values of
And
Conclusion:
Hence, the average velocity of the leaving water in the tank is

Fluid enters the suction line from reservoir 1 (left) through a sharp-edged inlet. The suction line is 10 cm commercial steel pipe, 15 m long. Flow passes through a pump with efficiency of 76%. Flow is discharged from the pump into a 5 cm line, through a fully open globe valve and a standard smooth threaded 90° elbow before reaching a long, straight discharge line. The discharge line is 5 cm commercial steel pipe, 200 m long. Flow then passes a second standard smooth threaded 90° elbow before discharging through a sharp-edged exit to reservoir 2 (right). Pipe lengths between the pump and valve, and connecting the second elbow to the exit are negligibly short compared to the suction and discharge lines. Volumes of reservoirs 1 and 2 are large compared to volumes extracted or supplied by the suction and discharge lines. Calculate the power that must be supplied to the…arrow_forward
