Compute the head loss in Example 4.11 by using the Hazen–Williams formula.

Data from example  4.11 Determine the head loss in a cast iron pipe that delivers water at a rate of 0.03 cm at 45°C between two points A and B. The pipe diameter and length are 150 mm and 300 m, respectively. If point B is 25 m higher than point A and both of the points have the same pressure, what is the pump head required to deliver water from point A to point B? The roughness of cast iron pipe is equal to 0.000 244 m.
