Question

Assume the substance is an ideal gas (R = 287 J/kg/K=0.287 kJ/kg/K) obeying the simple gas law p V = m RT,cv = 1.5 R and cp = 2.5 R. The specific volume at the initial state is given as vi-0.1565 m³/kg. (a) (15%) Sketch a graph of p-v indicating all 3 processes, all 3 states, and isobars & isotherms passing through all 3 states. Label the graph with all relevant numbers for temperature, pressure and specific volume. Note that the horizontal axis should be specific volume v in m²/kg not volume in m³. ) (15%) Sketch a graph of T-v indicating all 3 processes, all 3 states, and isobars & isotherms passing through all 3 states. Label the graph with all relevant numbers for temperature, pressure and specific volume. Note that the horizontal axis should be specific volume v in m³/kg not volume in m³ (c) (15%) Determine the mass of the ideal gas and all the missing values in the table below and write them in the given spaces in the table. Show all work. Do not write just final answers by solving these on a calculator or on a scrap paper. We want to see the steps and assumptions clearly. (d) (5pt) Is this a power cycle or refrigeration cycle? Explain your reasoning.
