What does g represent in g=1.27×108?
The pressure drop across the tube bundle, ΔPr=4G2N/2gr, is this formula, right? In the formula, N represents the number of tube passes, G represents the weight flow rate inside the tube (N/㎡h), r represents the specific gravity of hot water (N/m3), g represents the acceleration due to gravity (g=1.27×108) (m/h2), di represents the inner diameter (m), and L represents the length of the tube (m)
g represents the acceleration due to gravity (g=1.27×108) (m/h2)
