Consider a mass M is a distance L above the ground at constant temperature, TR. The mass is released, falls, and hits the ground. The kinetic energy just before it hits is converted to thermal energy due to the collision and is transferred to the ground by heat transfer. Using the Kelvin-Planck statement of the second law, demonstrate that this process is irreversible.
a heat pump maintains a temperature of 25degc inside a house. the house leaks 0.8 kw per degree temperature difference
a subway car leaves station a it gains speed at the rate of 2 ms2 for 6 seconds and then at the rate of 3 ms2 until it
Water is being heated in a vertical piston-cylinder device. The piston has a mass of 20 kg and a cross-sectional area of 100 cm2. If the local atmospheric pressure is 100 kPa, determine the temperature at which the water starts boiling.
a pump is used to move water from a lower reservoir to an upper reservoir. the water surface elevation in the upper
a truck travelling along a straight road at speed 20 km/hr increases its speed to 120 hr/hr in time 15 sec.If its acceleration is constant, determine the distance traveled.
calculate the total dv required to transfer between two coplanar circular earth orbits of radii r1 2 du and r2 5 du
Water enters a 10-cm diameter pipe at a uniform velocity V, it leaves the pipe at a non-uniform velocity of u= 10(1 - r^2/0.01) m/s, where r is in meters. Using the equation derived in class (10-2-14) find the magnitude of V and the mass flow rate of..
