6. If 8 lbs of a substance receives 240 Btu of heat at constant volume and undergo a temperature change of 150oF. What is the average specific heat of the substance during the process? (3 DECIMALS IN FINAL ANSWER PLS)
1. I just need the graph or figure of it. One pound of an ideal gas undergoes an isentropic process from 95.3psig and a volume of 0.6ft3 to a final volume of 3.6 ft3. If cp = 0.124Btu/lb-R and cv = 0.093 Btu/lb-R, determine the final temperature of the gas (0F) and the work done by the gas (Btu).

If cp = 0.124Btu/lb-R and cv = 0.093 Btu/lb-R, determine the final temperature of the gas (°F) and the work done by the gas (Btu). Draw a figure, or graph that will support the problem. Explain each step by step formula.
Suppose there are two identical gas cylinders. One contains the monatomic gas krypton (Kr), and the other contains an equal mass of the monatomic gas radon (Rn). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio KEr /KERN of the average kinetic energy of an atom of krypton to the average kinetic energy of an atom of radon. The answer should be a value.
QUESTION 43 Carbon dioxide (molar mass 44 kg/kmol) expands reversibly in a perfectly thermally insulated cylinder from 3.7 bar, 220 UC to a volume of 0085 m If the initial volume occupied was 0.02 m calculate the adiabatic index to 1 decimal place. Assume nitrogen to be a perfect gas and take cv = 0 63 k J / k g K.
1- Suppose you are operating a steam turbine where the steam leaving the turbine is at 5 bar. This steam contains 95 wt% vapors. If the shaft work produced by the turbine is 1100 kJ/kg and the high pressure, high temperature steam enters the turbine at 100 bar (abs), what is the temperature of the steam entering the turbine? If water at 10°C is supplied to the steam boiler to generate steam, how much heat is required per kilogram of steam produced? You may assume that heat losses from the turbine are negligible.
I have some things that need clarification based on the answer provided to this question. Firstly, the h1 value came out as 154.99 kJ/Kg for me not 153.318. Also, the values taken from the steam table for Vf and Vg for 5 degrees celcius and 6 degrees are different from what is on the steam table, I have attached a picture for this. For 5 degrees on the steam table it shows Vf as 0.00100008 and Vg as 147.011 and for 6 degrees it shows Vf as 0.00100011 and Vg as 137.633. Please clarify this and reply as soon as possible. Thanks
Using the following information, determine the vapor pressure of water at 300 °C. Note: We started this problem in week 6 lecture 3. Please refer to the lecture to get started on this problem. You only need to show your work starting from where the lecture left off. H₂0 at T = 179.88 degrees C the vapor pressure is PSAT = 10 bar. The enthalpy of vaporization is 2014.59 kJ/kg V = 0.1944 m³/kg V¹ = 0.001127 m³/kg The equation we left off on in class was, cpf 1 [P² psat dpsat pi psat Tf 1 ∆vapH (TF 1 RAZ Ti dT T2a
