Question 2. A gas flows through a long pipe of constant diameter. The outlet of the pipe is lower than the inlet, and the pressure of the gas at the outlet is higher than the inlet pressure. The gas temperature is constant throughout the pipe and the system is at steady state (Assume ideal gas behavior). How do: i. The mass flow rates at the inlet and outlet compare? ii. The densities at the inlet and outlet compare? iii. The volumetric flow rates at the inlet and outlet compare? iv. Is the change in potential energy and kinetic energy of the gas positive, negative, or zero?

Solve the following problem using the right Thermodynamics properties table.
A rigid, well-insulated tank contains a two-phase mixture of ammonia with 0.0022 ft³ of saturated liquid and 1.5 ft3 of saturated vapor, initially at p₁ = 70 lb/in². A paddle wheel stirs the mixture until only saturated vapor at higher pressure, p2, remains in the tank. Kinetic and potential energy effects are negligible. Determine the pressure p2, in lb/in², and the amount of energy transfer by work, in Btu. Step 1 * Your answer is incorrect. Determine p2, in lb/in². P2= i81.56 lb/in²
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 adiabatic index to 1 decimal place. Assume nitrogen to be a perfect gas and take cv = 0.63 k J / k g K
Carbon dioxide (CO₂) fills a closed, rigid tank fitted with a paddle wheel, initially at 80°F, 50 lb/in², and a volume of 1.6 ft³. The gas is stirred until its temperature is 500°F. During this process heat transfer from the gas to its surroundings occurs in an amount 2.6 Btu. Assume ideal gas behavior, but do not assume constant specific heats. Kinetic and potential energy effects can be ignored. Determine the mass of the carbon dioxide, in lb, and the work, in Btu.
