Explain in detail why some pistons are cam ground and or tapered.
What will be an ideal response?
Pistons can be ground in an oval shape around the skirts when viewed from the top and or tapered from the top to the bottom. The shapes are there to work with the effects of thermal expansion. After the piston heats up to normal operating temperature, it takes on a standard shape that fits the cylinder.

Answer the following statement true (T) or false (F)
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?
