WebNatural Circulation – Flow Rate The natural circulation flow rate in the loop under steady-state conditions is determined from the balance between the driving and the resisting forces. Driving force results from density difference between hot leg and cold leg of the loop. WebYou can calculate the turnover rate by dividing the gallons in your pool by the gallons per minute rate determined by your flow meter. This device measures the water flow through your pool’s recirculation system. This formula’s turnover rate is how long the pump and filtration system takes to circulate all the pool’s water. images of verna hillie

WebPN = New circulating pressure in psi PO = Old circulating pressure in psi SPM N = New pump rate in strokes per minute SPM O = Old pump rate in strokes per minute Example: Determine the new circulating pressure, psi using the following data. Present circulating pressure = 1800 psi Old pump rate = 60 spm New pump rate = 30 spm WebCalculate the recirculation flow rate required for ΔT = 5F with 100 feet of ¾” insulated copper pipe, and determine the pressure drop across the CircuitSolver® at that flow rate. Use the chart above for heat loss of 1800 BTU/h per 100 feet and the equation above for temperature drop ΔT = 5F.
