Question 1

What is a cusec?

Accepted Answer

A cusec equals 1 cubic foot per second (ft³/s). Used in US hydrology. 1 cusec = 28.3168 liters/second.

Question 2

How do cusec and cumec compare?

Accepted Answer

One cumec = 35.3147 cusecs. Cumec is metric (m³/s), cusec is imperial (ft³/s).

Question 3

How does pipe diameter affect flow rate?

Accepted Answer

Flow rate is proportional to the square of diameter. Doubling pipe diameter quadruples potential flow rate at the same pressure.

Question 4

What's the difference between volume and mass flow rate?

Accepted Answer

Volume flow (gallons/min) ignores fluid density. Mass flow (kg/s) accounts for density, important when density changes with temperature or pressure.
