Carbon Dioxide is contained in a piston-cylinder assembly and undergoes a cycle made of the fol- lowing processes: • Process 1-2: Constant volume from 1 bar, 300 K to 600 K • Process 2–3: Polytropic expansion with n=k until P3 = P1 • Process 3-1: Isobaric compression (a) Sketch the cycle on p-v and T-v coordinates (b) Determine the work and heat transfer in each process, in kJ/kg (c) Determine the type of cycle that this is. If it is a power cycle, compute the thermal efficiency. Otherwise, compute the coefficient of performance for a heat pump cycle.
Please do not rely too much on chatgpt, because its answer may be wrong. Please consider it carefully and give your own answer. You can borrow ideas from gpt, but please do not believe its answer.Very very grateful!

for steam, the specific ideal gas constant = 461.5 J/kg K A closed system is comprised of pure water substance initially at a temperature of 500 oC and a pressure of 20 MPa (state 1). The system undergoes an isochoric process whereby its pressure drops to 0.1 Mpa (state 2). For state 1 evaluate the specific volume assuming the steam behaves as an ideal gas and comment on your result.
An unknown material, m, = 0.21 kg, at a temperature of T, = 76 degrees C is added to a Dewer (an insulated container) which contains m2 = 1.1 kg of water at T2 = 21 degrees C. Water has a specific heat of c,,= 4186 J/(kg·K). After the system comes to equilibrium the final temperature is T= 30.5 degrees C. Input an expression for the specific heat of the unknown material. Cu What is the specific heat in J/(kg-K)?
Looking for velocity at the exit and mass flow rate. Show step by step solution please thank youu
Carbon dioxide (molar mass 44 kg/kmol) expands reversibly in a perfectly thermally insulated cylinder from 3.7 bar, 220 0C to a volume of 0.085 m3. If the initial volume occupied was 0.02 m3, calculate the gas constant to 3 decimal places. Assume nitrogen to be a perfect gas and take cv = 0.63 k J / k g K.

If the kinetic energy of the flywheel is dissipated as frictional heat at the shaft bearings which have a water equivalent of 2 kg, find the rise in the temperature of the bearings when the flywheel has come to rest. Calculate the greatest possible amount of the above heat which may be returned to the flywheel as high- grade energy, showing how much of the original kinetic energy is now unavailable. What would be the final r.p.m. of the flywheel, if it is set in motion with this available…
