Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Question

Water in an open metal drum is to be heated from room temperature (25 C) to 80 C by adding steam slowly enough that all the steam condenses. The drum initially contains 100 kg of water, and steam is supplied at 3 bar and 300 C. How many kilograms of steam should be added so that the final temperature of water in the tank is exactly 80 C? Neglect all heat losses from water.
There is a calorimeter composed of a thermally insulated container. Inside it are 1.2 kg of ice at −15 ∘C. How much mass of water at 60 ∘C needs to be added in the calorimeter for the final temperature to be 5 ∘C? If water vapor were introduced at 100 ∘C instead of water, how much mass of steam would have to be added for the final temperature to be 30 ∘C? What volume would the water vapor in the previous part occupy (before adding it to the calorimeter) if the pressure at which it is contained is 1.20 × 105 Pa? NOTE: The molar mass of water is 18 g / mol. ice = 2090 J / kg ∘C. water = 4180 J / kg ∘C. Lf, water = 3.33 × 105 J / kg. Lv, water = 2.26 × 106 J / kg
Many gyms and health clubs have steam saunas, which are small steam-filled rooms. Traditionally, steam saunas have a container of heated rocks.
