Determine the velocity of the flow of water @45C is flowing through a 3-in ID smooth pipe.
The friction loss for a 75 ft section of the pipe amounts to 2.4 lbf / lbm.
Two pipes, one of internal diameter (I.D.) 0.5 m and the other of I.D. 1 m, are connected as
shown in Fig. 3 to a pipe of I.D. 1.2 m. Oil with a density of 880 kg/m3 flows through the pipe
system at a total flowrate of 0.5 m3/s. If the liquid velocity in each of the two smaller-diameter
pipes is the same, calculate this velocity, the corresponding volumetric and mass flowrates in
the two pipes, and also the velocity in the large outlet pipe.
Determine the average velocity for water flow in a 2 in diameter pipe, Schedule 40 chlorinated polyvinyl chloride (CPVC) pipe (2.375 in outside diameter and 2.047 in inside diameter) carrying cold water at a volumetric flow rate of 40 gpm.
