A fluid flows through a pipe. Calculate the drop in piezometer level (h) in units of cm.

A fluid flows through a pipe. Calculate the drop in piezometer level (Δh) in units of cm. The flow is steady and fully developed. The fluid is Newtonian. The mean velocity is 0.4 m/s. The Reynolds number is 100,000. The relative roughness is 0.002. The length between piezometers is 50 m and the pipe ID is 3.0 cm. Choose the closest answer (cm): (a) 8, 

(b) 14, 

(c) 22,

(d) 28, 

(e) 34.
