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.

Steam leaves an industrial boiler at 645.3kPa and 151.2°C. A portion of the steam is fed through a throttling calorimeter and released to the atmosphere when the calorimeter pressure exceeds 104.3kPa. If the calorimeter's steam temperature is 113.8°C, a. What is the amount of moisture that is escaping from the boiler container? Show unit analysis & conversion. b. Calculate the mass of the saturated vapor if the mass of the saturated liquid is 15kg. Show unit analysis & conversion. @645.3kPa and 151.2°C: hf = 624.56kJ/kg hfg =2123.3kJ/kg @104.3kPa and 113.8°C: h2=2506.7kJ/kg
Steam generators are a type of heat exchanges that are used in power plants to generate steam at desired pressure and temperature (Fig. Q1.b). In a steam generator, saturated liquid water at 30°C enters a 60-mm diameter tube at the volume flow rate of 12 L/s. After exchanging heat with hot gas, the water changes to steam and leaves the generator at a pressure of 9 MPa and a temperature of 400°C. During this process, the diameter of the water/steam tube does not change.(iii) What is the exit velocity of the steam?

Problem 5. A 1000 cubic foot room is initially at standard temperature and pressure. A resistance heater in the room is consuming 1500W of electricity. What is the air temperature of the room after 3 hours? Assume the room acts as an isolated system. Hint: The specific heat of a substance is the amount of heat it takes to warm one unit mass of material by one degree. The specific heat of air (assuming constant volume) can be taken as C₂ = 700J/kg°C. This relates the total heat added to the system to its temperature rise.
