Problem 3  A 300-mm pipe is connected by a re ducer to a 100- mm pipe. See Figure 4 -02. Points 1 and 2 are a t the same elevation, the pressure at 1 is 200 kPa. The discharge Q is 30 liters per second flowing from 1 to 2 and the energy lost from 1 to 2 is equivalent to 20 kPa. a. Compute the pressure at 2 if the liquid is w water. ater. b. Compute the pressure at 2 if the liquid is oil (sp gr = 0.80). c. Compute the pressure at 2 if the liquid is molasses molasses (sp gr = 1.5).
