Question

oil is flowing through a tube that has two different cross-sectional areas. at position a where the radius of the tube is 7.0 cm, the mass flow rate of the oil is 0.025 kg/s. what is the mass flow rate at position b where the radius of the tube is 3.5 cm?

Answer 1

According to the continuity equation, the rate at which mass enters the system equals the rate at which mass exits in any steady state process.

An equation that explains the movement of a particular quantity is a continuity equation, also known as a transport equation. Although it can be applied generally to any significant quantity, it is extremely simple and useful when used with preserved quantities.

The radius is seven centimeters, and the mass flow rate is 0 to 5 kg/s. Find the mass flow rate at a point with a 3.5 cm radius. We can consequently deduce that based on the equation. As we all know, the mass flow rate is constant.

If the rate of mass entering and leaving the system is equal, the rate of mass leaving the system should be processed.

The mass flow rate air section A and the mass flow rated section B are equivalent, according to the continuity equation. Mass flow rate in section B is therefore 0.02, or five kilograms per second.
