H.W1: Warm air is contained in a piston-cylinder assembly oriented horizontally as shown in Figure below. The air cools slowly from an initial volume of 0.003 m’ to a final volume of 0.002 m². During the process, the spring exerts a force that varies linearly from an initial value of 900 N to a final value of zero. The atmospheric pressure is 100 kPa, and the area of the piston face is 0.018 m². Friction between the piston and the cylinder wall can be neglected. For the air, determine the initial and final pressures, in kPa, and the work, in kJ.

Patm 1. Initially; the piston sits on the stops and the linear spring exerts no force, the specific volume is 0.05 m /kg and the pressure is 125 kPa. Atmospheric pressure is 100 kPa, mass of the piston is 102 kg, and area of the piston is 200 cm?. The linear spring exerts a force on the piston in such a way that the specific volume becomes 0.08 m'/kg when the pressure reaches 200 kPa. Heat is transferred to the water until its temperature is 115 °C. Calculate work and heat transfer, showing the process on a P-v plot. Hint: In the final stage, the temperature is 115°C, but the pressure is not given. You need to find P and v using the tables and P-v plot.
Q5: a hydraulic press is used to compact powdered samples. The device is made of two interconnected cylindrical chambers filled with oil if density psubscripto anc closed by two pistons. The small chamber on the right has diameter d and the large chamber on the left has diameter 5d. A lever is attached to the piston pushing down on the fluid in the small cylinder. The horizontal lever is hinged on the left, at distance L from the small piston, and a force of magnitude Fsubscript0 is applied vertically down at distance 2L from the hinge (Fig.5). You may assume that the lever and pistons have negligible mass. a. Determine the magnitude of the force Fin that the small piston exerts on the fluid in the small cylinder.

Task 2 A frictionless piston fitted inside a cylinder containing gas at a pressure of 200 kPa, volume of 1 liter and temperature of 25 ° C. Choose one gas from Task 1, the gas is to be compressed in the system and the final volume is 0.5 liter. Work is done to move the piston and heat is transferred to the cooling system around the cylinder. Illustrate the importance of expressions for work done in thermodynamic processes by applying first principles while calculating the work done when the expansion is ADIABATIC, ISOTHERMAL and POLYTROPIC for different n= (1.2, 1.3, 1.4, 1.8, 1.9). Discuss the effect of varying n on the calculated boundary work.
In the two-pipe system, water flows continuously from the inner pipe and air from the outer pipe (steady-state). ˙The pressure change in both pipes is negligible. In addition, heat interaction with the environment, kinetic and potential energy changes are also neglected. In this system shown in Figure 1, the water flowing from the inlet number 1 is in the state of saturated vapor (gas). In this case, calculate the outlet temperature (T2) for the given system, using the ideal gas approximation for air. (it should be solved iteratively.) (Please solve it on paper and solve it line by line. When you type it, it becomes too complicated to understand. Also please explain your solution and don't write too close. Thank you for your effort)
