Mechanical-Energy Balance and Friction Losses. Hot water is being discharged from a storage tank at the rate of 0.223 ft³
/s. The process flow diagram and conditions are the same as given in Example 5.1-6, except for different nominal pipe sizes of Schedule 40 steel pipe as follows: The 20-ft-long outlet pipe from the storage tank is 1
-in. pipe instead of 4-in. pipe. The other piping, which was 2-in. pipe, is now 2.5-in. pipe. Note that a sudden expansion now occurs after the elbow in the 1
-in. pipe to a 2
-in. pipe.
