FAQs
How do you calculate GPM based on PSI and pipe size? The relationship between pressure (PSI), pipe size, and flow rate (GPM) involves complex fluid dynamics equations. There isn’t a simple formula that directly calculates GPM from PSI and pipe size due to factors like pipe length, material, and friction. Professional engineering calculations or specialized software are often used.
