CPP 1.5A piston-cylinder device, with a set of stops on the top, initially contains 3kg of air at 200kPa and 27°C. Heat is now transferred to the air, and the piston rises until it hits the stops, at which point the volume is twice the initial volume. More heat is transferred until the pressure inside the cylinder also doubles. Determine: P 1.5.1 the work done; 1.5.2 the amount of heat transfer for this process. 1.5.3 Explain step-by-step the process from the moment that the heat is transferred to the air. m= 3kg P₁ = 200k pa 1773 = 300k
Problem 1. Initially, 0.05kg of air is contained in a piston cylinder device at 200 °C and 1.6 MPa. The air then expands at constant temperature to a pressure of 0.4 MPa. Assume the process occurs slowly enough that the acceleration of the piston can be neglected. The ambient pressure is 101.35kPa. (i) Determine the work (kJ) performed bt the air in the cylinder on the piston. (ii) Determine the work (kJ) performed by the piston on the ambient environment. Neglect the cross- sectional area of the connecting rod. (iii) Determine the work transfer (kJ) from the piston to the connecting rod. Neglect friction between the piston and cylinder. Assume that no heat transfer to or from the piston occurs and that the energy of the piston does not change.
Four pounds of steam initially dry and saturated expand isentropically in a non-flow process from an initial pressure of 275 psia to a final pressure of 125 psia. Find its quality and determine the work done in BTU/lb.
3. An empty 100-L tank is connected to a line flowing air (an ideal gas) at 300 K and 6 MPa. The valve is opened and the air starts to flow into the tank. The valve is closed when the pressure inside reaches 5 MPa. This filling process occurs so fast that it can be assumed as adiabatic (i.e., no heat transfer). At the point when the valve is closed, what is the temperature and mass of air inside the tank?
(Section B) A thermodynamic system contains piston-cylinder arrangement with 0.02 m3 of air at 50°C and 400 kPa. During this process heat is added in an amount of 50 kJ and the work is done by a paddle wheel until the temperature reaches 700°C. If the pressure iss kept constant how much paddle-wheel work must be added to the air?
Two rigid tanks A and B are connected by a valve. Tank A contains 0.6 of water at 550 kPa and 43 percent quality. Tank B contains 0.81 of water at 200 kPa and 700 oC. The valve is now opened and the two tanks eventually come to the same state and reach thermal equilibrium with the surroundings at 35 oC. Calculate the followings: a) The final pressure in the system (kPa); b) the amount of heat transfer (kJ). Submit your solution by adding (a) + (b) = View solution Format answer : 8599.6782

A piston-cylinder device initially contains CO2 at 200 kPa and 400°C and the total enclosed volume is 300 litres. Due to heat loss, the piston moves downwards to a position where it sits on a pair of stoppers and its final enclosed volume is 150 litres. Further heat loss leads to the pressure being reduced to 160kPa. Workout 1) the final temperature, 2) the total work done by CO2 and 3) the total heat transferred to CO2. Also make some comments on the result of heat and create a schematic p-v diagram of the process. The following assumptions are to be made: CO2 is a perfect gas and its molecular mass is 44kg/kmol. The ratio of specific heat capacities, γ (gamma) is 1.3 The volume occupied by the stoppers is to be ignored. There is no leakage in the system There is no friction between the cylinder and piston walls and the piston moved slowly at the same speed therefore, no acceleration. For the conversion from Celsius to Kelvin, use 273 Use 8314.5 J/kmol.K for the universal gas…

A mass of 5.1 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder at 100 kPa. Initially, 2.9 kg of the water is in the liquid phase and the rest is in the vapor phase. Heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 300 kPa. Heat transfer continues until the total volume increases by 22 percent. Determine:a) the initial temperature (oC),b) the final temperature (oC),c) the specific volume of water when the piston first starts moving (m3/kg), andd) the work done during this process (kJ).
