A confined quantity of air undergoes two thermodynamic processes departing from an initial equilibrium state where the temperature is 20°C, the absolute pressure is 1bar, and the volume is 0.2m3. First, the volume of the system is doubled by an isobaric process. Then, the volume is decreased back to the initial value through a process where the relation P-V1.4 is kept constant. You may assume average values for the particular heat capacities (cp and cv) to:
(a) Sketch the processes in a P-V diagram.
(b) Determine the temperature of the three states in K.
(c) Calculate the total work in kJ.
(d) Compute the total heat transfer in kJ.
Air enters in a compressor operating at steady state along with a volumetric flow rate of 37 m³/min at 136 kPa, 305 K and exits with a pressure of 680 pPa and a exact volume of 0.1
how to solve A • B x C = A x B • C?
In this case both source and screen are effectively at infinite distance from the diffracting device. Basic types: Diffraction at single slit, double slit and diffracting gratin
For SHM to occur, three conditions must be satisfied. 1.There must be a position of stable equilibrium. At the equation in equilibrium potential energy is minimized. That is,
