Assuming an atmospheric pressure of 100 kpa, the density of water equal to 1000 kg/m3, and the gravity equal to 9.81 m/s2, the pressure at the bottom of a pool of water with a depth of 9.3 m is equal to:

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
