Question

The flow data for a valve is given, and the valve's Cv needs to be calculated. What is the purpose of the Cv in this context?

a) It represents the valve's material strength
b) It denotes the valve's manufacturing cost
c) It quantifies the valve's flow capacity
d) It measures the valve's external dimensions

Answer 1

The Cv in this context refers to the valve's flow capacity. It quantifies the amount of fluid that can pass through the valve.

Step-by-step explanation:

The Cv in this context refers to the valve's flow capacity.

It quantifies the amount of fluid that can pass through the valve.

Cv stands for the flow coefficient and is a dimensionless value used to compare the flow capacities of different valves at the same pressure drop.

The larger the Cv value, the higher the flow capacity of the valve.
