a 150-m length of smooth horizontal pipe is attached to a large reservoir. what depth, d, must be maintained in the reservoir to produce a volume flow rate of 0.0084 m3 /s of water? the head loss is 5.15 m. the inside diameter of the smooth pipe is 90 mm. the inlet is sharp-edged.

Answer :

The calculated value is P 2 = 500 Pa. The amount of fluid travelling through a specific cross sectional area per unit time is known as the volume flow rate Q of a fluid.

1 atmosphere (101.3 kPa), or 14.696 psia at 32 0F, is the standard flow rate (0 0C). The volume of fluid that actually moves through a given site at a given pressure and temperature is known as the actual flow rate.

We may determine the velocity at another point using the equation of continuity. There is a one.

​ \s v \s1 \s​ \s =a \s2 \s​ \s v \s2

​⇒10×1=5×v \s2 \s​

⇒v \s2 \s​ \s =2m/s

The Bernoulli's theorem states that for water at a certain height, P= 2 (v 1 2 v 2 2)

​P= 2 1000(1 2 2 2 ) = 1 500 Pa, P 2 P 1 = 1 500 Pa, P 2 2000= 1 500 Pa, and P 2 = 500 Pa.
