Velocity of fluid flow v 20m s. Q 0 0201 m 2 3 30 m s q 0 0663 m 3 s. Q 193 7 c d2 63 s0 54 where. The flow rate can be converted to liters per second using.

The depth of the water is also measured at each point. Moreover the flow rate depends upon the channel from which the liquid is passing or the area of the pipe and the velocity of the liquid. 1 m 3 s 1000 l s. You can calculate the flow rate volume and pressure in a water tank using formulas from physics.

Volume is the amount of space that an object takes up and may be measured in liters gallons or cubic meters. 2 water is flowing down an open rectangular chute. Area of cross section of the pipe a 3 14 4 0 03 0 03 a 0 785 0 0009 a. Flow rate is the measure of the volume of liquid that moves in a certain amount of time.

The flow rate of the water through the circular pipe is 66 3 l s. In the simplest method a current meter turns with the flow of the river or stream.
