A liquid flows upward through a valve situated in a vertical pipe. Calculate the differential pressure (kPa) between points A and B. The mean velocity of the flow is 4.1 m/s. The specific gravity of the liquid is 1.2. The pipe has constant diameter. The valve has a minor loss coefficient of 4.0. Assume that major losses (i.e., head losses in the pipe itself) can be neglected. Point A is located 3.2 meters below point B. Choose the closest answer (kPa): 

(a) 3.4, 

(b) 6.6, 

(c) 40, 

(d) 65, 

(e) 78.
