1. Atank containing 20kg of water at 20C° is fitted with a stirrer that delivers
work to the water at the rate of 0.25 KW. How long does it take for the
temperature of the water to raise to 30C° if no heat is lost from the water?
For water CP=4.18 KJ/Kg.C° 1.
2. A steel casting weighting 2 kg has an initial temperature of 500 Co; 40 kg
of water initially at 25 C° is contained in a perfectly insulated steel tank
weighting 5 kg. The casting is immersed in the water and the system is
allowed to come to equilibrium. What is final temperature? Ignore effects
of expansion or contraction. And assume constant specific heats of 4.18
KJ/Kg-1 .K° for water and 0.5 KJ/Kg .K°-1 for steel.
3. One kg of liquid water at 25 co.
