Repeat Problem 14.5 for a certain Utah coal that contains, Repeat Problem 14.5 for a certain Utah coal that contains, according to the coal analysis, 68.2% C, 4.8% H, 15.7% O on a mass basis. The exiting product gas contains 30.9% CO, 26.7% H2, 15.9% CO2 and 25.7% H2O on a mole basis. Is this […]

Repeat problem 2.72 if the flow inside the apparatus Repeat problem 2.72 if the flow inside the apparatus is liquid water, ρ ≅ 1000 kg/m3, instead of air. Find the pressure difference between the two holes flush with the bottom of the channel. You cannot neglect the two unequal water columns. Is this the question […]

One ton of liquid water at 80°C is brought One ton of liquid water at 80째C is brought into a well-insulated and well-sealed 4-m X 5-m X 6-m room initially at 22째C and 100 kPa. Assuming constant specific heats for both the air and water at room temperature, determine (a) The final equilibrium temperature in […]

Saturated liquid ethane at 2.44 MPa enters (SSSF) a heat Saturated liquid ethane at 2.44 MPa enters (SSSF) a heat exchanger and is brought to 611 K at constant pressure, after which it enters a reversible adiabatic turbine where it expands to 100 kPa. Find the heat transfer in the heat exchanger, the turbine exit […]

One ton (1000 kg) of liquid water at 80°C One ton (1000 kg) of liquid water at 80째C is brought into a well-insulated and well-sealed 4-m = 5-m = 6-m room initially at 22째C and 100 kPa. Assuming constant specific heats for both air and water at room temperature, determine the final equilibrium temperature in […]

One technique for expansion inside the turbine to be reversible One technique for operating a steam turbine in part-load power output is to throttle the steam to a lower pressure before it enters the turbine. The steam line conditions are 200 lbf/in 2, 600 F, and the turbine exhaust pressure is fixed at 1 lbf/in […]

Saturated liquid water at 1000 kPa Saturated liquid water at 1000 kPa flows at 2 kg/s inside a 10 cm outer diameter steel pipe and outside of the pipe is a flow of hot gases at 1000 K with a convection coefficient of h = 150 W/m2 K. Neglect any ?T in the steel and […]
