Question

The rate of flow of the liquid is the product of

• A. Area of cross section of the liquid and velocity of the liquid.
• B. Length of the tube of the flow and velocity of the liquid
• C. Volume of the tube of the flow and velocity of the liquid
• D. Viscous force acting on the liquid layer and velocity of the liquid

Answer 1

The correct option is A Area of cross section of the liquid and velocity of the liquid.

Flow rate is the quantity of fluid flowing in the specified time. It is expressed in litres per meter (lpm)
$\Rightarrow Q=AV$
$\Rightarrow Q=\left(\text{area of cross section}\right)\times \left(\text{velocity of liquid}\right)$
