A rigid tank A of volume 0.6 m3 contains 3 kg water at 120oC and the rigid tank B is 0.4 m3 with water at 600 kPa, 200oC. They are connected to a piston cylinder initially empty with closed valves. The pressure in the cylinder should be 800 kPa to float the piston. Now the valves are slowly opened and heat is transferred so the water reaches a uniform state at 250oC with the valves open. Find the final volume and pressure and the work and heat transfer in the process.
Calculate the specific weight of toluene at a place where the acceleration of gravity is 32.2 ft/s^2or 9.81 m/s^2. Express your answer in both lbf/ft^3 and kg/m^3. Repeat this for Mars whre the acceleration due to gravity is 37.5% of that on Earth.
A closed, rigid tank is filled with a gas modeled as an idea gas, initially at 27 degrees C and a gage pressure of 300 kPa. The gas is heated, and the gage pressure at the final state is 367 kPa. Determine the final temperature, in C. The local atmos..
