Prob3 Consider a laminar flow that flow rate Q=0.2 ft³/s; v = 6.55 * 10.5 ft²/s. Find pipe diameter D=? [ft]

The figure shown below is a series pipeline system used to draw a fluid from a lower source open tank to a higher destination open tank . The flow and geometric layout for the system are listed below: Fluid: water       Volume flow rate: Q=0.015 m3/s Elevation difference:  h=8.0m of two free surfaces Suction line:                      DN100 Sch. 40 Steel pipe                      Length: Ls=2.0 m                      Valve1: hinged disc type foot valve                      Entrance type: well-rounded Discharge line:                           DN80 Sch. 40 Steel pipe                           Length: Ld=100 m                           Valve2: full open gate valve                           Elbows:  90ο long radius elbow   (1)  Select the simplified general energy equations for section 1 and 2_________       A.     B.     C.     D.

A water diffuser is constructed like that in the figure below. Diffuser wall 2 m Flow Entrance 7 m Exit The volumetric flow rate at the entrance (per meter depth into the plane of the image) is 14.0 m2/s and the pressure difference Pexit - Pentrance = 350 kPa. What is the expansion angle in degrees? i
