A vapor compression refrigeration cycle removes 25 kW of heat from a cold space. Ammonia enters the compressor as a saturated vapor at 175 kPa. It exits the condenser as a saturated liquid at 1600 kPa. The compressor efficiency is 75%. Find the coefficient of performance and the mass flow rate. Sketch the cycle on a T-s diagram.

Character Replacement. Using StringBuilder, create a program to input a string from the user and convert it to (a) reverse case (reverse the case of all characters), (b) only lowercase characters and (c) only uppercase characters. You are not allowed to use toUppercase or toLowercase for this question. Let’s examine some bit patterns and ASCII codes: The uppercase character ‘A’: 0100 0001 (ASCII Code 65) The lowercase character ‘a’: 0110 0001 (ASCII Code 97) From these examples, it is evident that uppercase and lowercase characters differ by one bit (bit 6, or by 32). You can easily convert a character from uppercase to lowercase (or vice versa) by doing a bitwise exclusive or (XOR) operation with the value 32 (2^6). You can do an exclusive or in Java by using the carat (^) symbol.

The 800 kg roller coaster is released from rest at A. Only kinetic energy and potential energy due to gravity are involved. (i) Determine the speed of the roller coaster at B. (10 pts.) (ii) Determine the minimum height $h$ of point A so that the car travels around the loop at B without leaving the car for this height. (15 pts.) (iii) Find the velocity of the car at C for this height $h$ of A. (8.5 pts.) Hint: For the roller coaster to not leave the track at B, the normal force should be equal to zero.
