The function below takes a single integer input: number. complete the function to return a boolean indicating whether the number is prime. recall that a number is prime, if it isn't evenly divisible by any integer other than 1. the recommended way to implement this function is to iterate (using a for loop) through all of the numbers greater than one, but less that number. (the range() function is your friend, here.) for each of those numbers, test if they evenly divide number using the % operator. if any of them do divide evenly, then return false. if you get through all of the numbers without any dividing evenly, then it must be prime, so return true.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
