Find flow rate, velocity
Thread Content
The medium is steam; given the nominal pipe diameter, pressure, and temperature, can the flow rate be calculated? If not, what else is required?
It can be calculated, but that is a range value; it’s better to determine the allowable pressure drop for pipeline transportation
Is there no pressure drop, so flow occurs due to the pressure difference? P
It has no direct relation to temperature and pressure; you only know the pipe diameter, so it’s of course impossible to calculate the flow rate. According to Bernoulli’s equation, the pressure drop should be known; by then converting it to flow velocity, the flow rate can be determined.
I only know that the flow coefficient of the valve is calculated based on the flow rate, in order to boost it:$
