Programming Assignment 4 ENGR 3, Summer Session B 2006 Due: Tuesday, September 5 11:59pm Instructions: Complete the following parts. Turn these programs in using the command: “turnin [email protected] idealgas.m container.m tank.m aero.m” Part A (10 points) Name your script file idealgas.m . Engineers often need to estimate the pressure exerted by a gas in a container. The ideal gas law provides one way of making the estimate. The law is P = nRT V Equation 1. The ideal gas law More accurate estimates can be made with the van der Waals equation: P = nRT V − nb − an 2 V 2 Equation 2. Van der Waals equation where the term nb is a correction for the volume of the molecules, and the term an 2 / V 2 is a correction for molecular attractions. The values of a and b depend on the type of gas. The gas constant is R, the absolute temperature is T, the gas volume is V
