Water is being pumped from a pressurized tank to an open elevated tank as shown in the figure below. The system consist of a total length of 90m commercial steel (new) pipe with 15cm internal diameter with two regular flanged elbows delivering a volume flow rate of 40 I/s. Determine head added by the pump.

Strain energy

The term strain indicates the variation in an object's length, area, and volume when the object is subjected to an external force. The external force may be of normal, shear, moment, torque, etc. The strain in an object depends on the types of external force and cross-section of the object. Mathematically, the evaluation of strain can be obtained with the help of elastic constants.
