The HazenWilliams hydraulic formula for the massflow rate m

The Hazen-Williams hydraulic formula for the mass-flow rate, m through a pipe of diameter D and length L is given by m = K rho D^2.63 (delta_p/L)^0.54 where delta_p is the pressure drop and rho is the liquid\'s density. What are the base dimensions, SI units and US customary units of the constant K?

Solution

Solution:

In this equation K is nothing but a conversion factor for the various unit systems present like Si units, US customary units etc.

The value for K in SI units is 0.849

The value of K in US cusomary units are 1.318
