The water in the two tanks of Problem 3.214 receives heat transfer from a reservoir at 300?C. Find the total entropy generation due to this process.
Problem 3.214
Two rigid tanks are filled with water (Fig. P3.214). Tank A is 0.2 m3 at 100 kPa, 150?C and tank B is 0.3 m3 at saturated vapor of 300 kPa. The tanks are connected by a pipe with a closed valve. We open the valve and let all the water come to a single uniform state while we transfer enough heat to have a final pressure of 300 kPa. Give the two property values that determine the final state and find the heat transfer.
Calculate the pressure at the clay-sand interface for two cases:1) clay on top of the sand and 2) clay on the bottom of thevertical sand column.
A clay ball (m=0.82 kg) is thrown at a metal target (M=1.72 kg) that is suspended from a cable. The ball is released 1.5 m above teh ground at an angle of 32 degrees.
Consider one-dimensional transient conduction in a slab of thickness L. Initially, the entire slab is at temperature Ti and both surfaces are at temperature Ti. At time t = 0, the left surface (x = 0) temperature is increased to Ts. Find the tempe..
A particle is traveling in a straight line at a constant speed of 22.9 m/s. Suddenly, a constant force of 10.7 N acts on it, bringing it to a stop in a distance of 63.6 m.
