There are many correlations for predicting boiling heat transfer coefficient. The correlation given by Foster and Zuber (1955) can be used to estimate pool nucleate boiling coefficients (h) in the absence of experimental data, as shown below. 0.79 0.45040 C Pi h =0.00122 (T.-T.) (p. - p.)* Estimate the heat-transfer coefficient for the pool cooling of water at 1.98 bar, from a surface at 125 °C. Check that the critical flux is not exceeded.

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.
