14:440:127– Introduction to Computers for Engineers Homework Assignment 02 Rutgers University, Fall 2010 Instructor- Brenda V. Cortez INSTRUCTIONS: You are required to submit a .m file through Sakai. The naming conven- tion for your file is the following, and same as before: recSECnum netID HW##.m (i.e. rect00 bcortez HW02.m). recSECnum is 01- > 14 netID is your username Grading Rubric: 5 questions: 3 randomly selected questions get graded & if you get 2 wrong, you fail . 1 Interpolation Consider a gas in a piston cylinder device in which the temperature is held constant. As the volume of the device was changed, the pressure was measured. The volume and pressure values are reported in the following table: Volume, m 3 Pressure, kPa, when T = 300 K 1 2494 2 1247 3 831 4 623 5 499 6 416 a) Use linear interpolation to estimate the pressure when the volume is 3.8 m 3 . b) Use the cubic spline interpolation to estimate the pressure when the volume is 3.8 m 3 . c) Use linear interpolation to estimate the volume if the pressure is measured to be 1000 kPa.
