Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

The manufacturer of the device claims that it accepts a heat transfer at a rate of QH = 3.0 kW from a low-grade source of geothermal heat at TH = 80ºC and rejects heat at rate QC to the atmosphere at TC = 20ºC. The device operates at steady state and produced work at a rate of W= 2.5 kW. There are no other heat or work transfers from the device. a.) What is the rate at which the device rejects heat to the atmosphere, QC ? b.) Is this device possible? Justify your answer using an entropy balance.
1. An engine with a cylinder volume of 250 cc and a volume at top dead centre of 25 cc uses a thermal cycle where the initial stage is an isentropic adiabatic compression process with the equation pvY = C. It is known that the initial conditions are 1 bar and 30°C. After that, a combustion process takes place in which heat is supplied at a constant volume. The heat given is 80 KJ/kg and if the specific heat at constant volume is known to be 0.718 kJ/kg K, determine the maximum temperature and pressure that occur? 2. Air with a mass of 3 kg is heated at constant volume from 25°C to 120°C. The process then takes place at constant pressure so that the gas has a temperature of 550°C. Determine the heat required and the entropy change that occurs during the process? (Air: Cp = 1.005 kJ/kg.K and y = 1.4; and assume Cp does not change with temperature). Known that initial volume is 50 ml and the last volume is 300 ml.
Thermodynamics
A system consisting of a gas contained in a cylinder with a frictionless piston is taken around the closed path a→b→c→a where the process c→a is isothermal. During the closed cycle, the system expels 150 J to the environment. If the work done on the system during the isobaric leg b→c of the cycle is 250 J, what is the heat expelled/absorbed by the gas in the isothermal leg c→a in J.
