Concept explainers

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.

A piston-cylinder assembly contains a mystery substance that undergoes a series of processes. Process 1-->2: Constant pressure process at 5bar from v1=.07m3/kg to v2=.12m3/kg Process 2->3: Constant volume process to saturated vapor Process 3->4: Constant temperature process to quality of 50% Process 4->5: Constant volume process to 5bar Sketch the processes on Pt, Pv, and Tv, plots. Lable the axes including property values; use closed dots to show the states, use solid lines to connect the states, add number and arrows to make clear the states numbers and process directions.

Solve it correctly please.
Consider the series of processes shown in the p-V diagram below for a piston-cylinder system. Given the diagram information, determine the net work for the process from State 1 to State 3, in units of [kJ]. Specify whether the net work is into or out of the system, per our convention.
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.
Consider a sealed, rigid container of 10 kg of water vapor at 25°C and 80 kpa. A paddle wheelwith a power rating of 1 kW is operated within the tank for 30 minutes. During that time 7 kJ ofheat are lost to the surroundings. a.) Define the system. b.) What types of energy transfer occur? c.) What is the net energy change of the system?
