The Figure shown below is a parallel pipeline system with two branches used to supply lubricating water to the bearings. The main line and two branches use the same size of pipes. The pressures at section 1 and section 2 are   and  ,  respectively. The resistance coefficients for two bearings are   and  .  The cross section areas of two branch pipes are   .  The energy loss caused by friction can be ignored. The energy loss caused by one bend is  . (3)   Calculate the energy loss    for branch a

A pressurized tank and piping system are shown in the figure. The tank pressure is maintained at 175 kPa. The line is made of 12 m of 1 std type M copper tubing and it conveys gasoline (octane). What is the expected flow rate through the line? All fittings are soldered (same as flanged) and regular. 4 m 175 kPa 1 m

Example -5.2- It is required to pump cooling water from storage pond to a condenser in a process plant situated 10 m above the level of the pond. 200 m of 74.2 mm i.d. pipe is available and the pump has the characteristics given below. The head loss in the condenser is equivalent to 16 velocity heads based on the flow in the 74.2 mm pipe. If the friction factor = 0.003, estimate the rate of flow and the power to be supplied to the pump assuming n = 0.5 Q (m³/s) 0.0028 0.0039 0.005 0.0056 0.0059 Ah (m) 23.2 21.3 18.9 15.2 11.0

It is assumed that the pipe diameter is equal to the friction factor of 0.03. Because theratio of the LIDpipe is large, the minor losses are ignored. Determine the flow in or out of each reservoir!
