A well-insulated rigid tank of volume 8 ft3 initially contains carbon dioxide at 1808F and 40 lbf/in.2 A valve connected to the tank is opened, and carbon dioxide is withdrawn slowly until the pressure within the tank drops to p. An electrical resistor inside the tank maintains the temperature at 1808F. Modeling carbon dioxide as an ideal gas and neglecting kinectic and potential energy effects, (a) determine the mass of carbon dioxide withdrawn, in lb, and the energy input to the resistor, in Btu, when
p 5 22 lbf/in.2
(b) plot the quantities of part (a) versus p ranging from 15 to 40 lbf/in.2
How can you calculate the energy input in the resistor without using any software?
