. What is a person’s cardiac output if the stroke volume is 75ml and the average resting heart rate is 70bpm?
cardiac output = 220/70
cardiac output = 220-75
cardiac output = 75+70
cardiac output = 75x70

Oxygen undergoes an isentropic expansion from 120 degree c and 280 kpa absolute to 140 kpa absolute. determine the final temperature of the oxygen and the amount of work per kg of o_2 produced in the process if it is adiabatic.
