He surface of a cylinder (d = 10 mm) is maintained at 117 °c. fluid flows perpendicularly to the cylinder axis (cross flow). the fluid (37 °c) flows at 5 m/s. for three different fluids (atmospheric air, saturated liquid water, and engine oil), calculate the heat transfer rate per unit length using the churchill-bernstein correlation.

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.

The characteristic roots of a dynamic system are: 1.7920 1.8160 i, -1.7920 1.8160 i, -0.4160 what is the order of this system? what are the settling time and damping ratio of the system?

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.
