5.3 Activity: Determining Volume and Pressure

a. Take any measurements needed to determine the volume and pressure of air in the

system at all four points in the engine cycle. You should do this rapidly to avoid air

leakages around the piston and summarize the measurements with units in the space

below.

b. Next you can use your measurements to calculate the pressure and volume of the system

at point a. Show your equations and calculations in the space below and summarize your

results with units. Don't forget to take the volume of the air in the tubing and can into

account!

c. Use the measurements at point b to calculate the total volume and pressure of the air in the

system at that point in the cycle. Show your equations and calculations in the space below

and summarize your results with units.

d. What is the height, y, through which the added mass is lifted in the transition from b to c?

e. Use the measurements at point c to calculate the total volume and pressure of the air in the

system at that point in the cycle. Show your equations and calculations in the following

space and summarize your results with units.
