Steam, with a specific internal energy of 1205 Btu/lbm, is flowing through a pipe located 15 ft above the ground. The velocity of the steam in the pipe is 200 ft/s. Determine the total internal energy, the kinetic energy, and the potential energy of 2.50 lbm of steam in the pipe.

Given: m = 2.50 lbm; z = 15ft; V = 200 ft/s; u = 1205 Btu/lbm Assume: g = 32.174 ft/s2 What will be an ideal response?
