• ### Flow Rate Measurement in Liquids with Pressure Transducers

We can solve for k by simply dividing the flow rate by the square roof of its associated pressure drop. From the top line of the table: k = GPM/√ (ΔP) k = 640/10 = 64. We can verify this by using the new value of k to determine the flow rate, Q, in another part of the table, say at 25 In H2O: Q = 64 (5) = 320 GPM.
