Carbon dioxide enters an adiabatic nozzle steadily at 1 MPa, 530 oC, and mass flow rate of 5,227 kg/h and exits the system at 102 kPa and 427 m/s. Considering the nozzle having an inlet area of 43 cm2, calculate the inlet velocity in m/s (Give your answer with three decimals, and do NOT enter units!!!).

What is work? how much work is done to move an object 0 meters?

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?

Work = force × a. work b. energy c. distance d. momentum
