The program should perform the following tasks: • print a greeting to the screen stating what the program does. • ask the user to enter a pressure value in mpa from the keyboard. o only 5 mpa and 10 mpa will be valid entries. • based on the user’s pressure value, open/read in the corresponding data file. • provide capability to read a temperature value from the keyboard and interpolation to estimate data values. • repeat interpolating values until user quits. o you may choose the method for the user to indicate that he/she is ready to quit

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Fluids at rest possess no flow energy. a)- true b)- false

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
