Part One • A hotel salesperson enters sales in a text file. Each line contains the following, separated by semicolons: o The name of the client, o the service sold (such as Dinner, Conference, Lodging, and so on), o the amount of the sale o and the date of that event. • Prompt the user for data to write the file. Part Two • Write a program that reads the text file as described above, and that writes a separate file for each service category, containing the entries for that category. Name the output files Dinner. txt, Conference. txt, and so on. • Enter the name of the output file from Part One as a command line argument. Both Parts • For all programs, catch and handle the Exceptions appropriately and validate the input data where needed. • Display an error if the sales file does not exist or the format is incorrect. • Also, create your own exception to handle "unknown transaction" exceptions.

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.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
