Question

Water is stored in a tank which has vent open to the atmosphere. The water level is 1.0 m below the top the tank and the water is 4 m deep. A siphon with .03 m ID is used to remove water from the tank. The siphon discharge is 6.0 m below the top of the tank. Neglect the friction loss of water through the siphon. Determine the flow rate of water in unit of m^3/s.

Answer 1

Answer:

6.99 x 10⁻³ m³ / s

Explanation:

Th e pressure difference at the two ends of the delivery pipe due to atmospheric pressure and water column will cause flow of water.

h = difference in the height of water column at two ends of delivery pipe

6 - 1 =  5 m

Velocity of flow of water

v = √2gh

= √ (2 x 9.8 x 5)

=  9.9 m /s

Volume of water flowing per unit time

velocity x cross sectional area

= 9.9 x 3.14 x .015²

= 6.99 x 10⁻³ m³ / s
