Modularizing our code has many advantages: Code Re-use, breaks complex problems into smaller more manageable problems, provides for abstraction. When we build are modules correctly they can be re-used across many different applications/systems. Also, programmers can use Methods in their applications without having to know the details of how each Method was programmed, this is abstraction. We have used Java standard built-in modules without having to know the details of how it was programmed already (abstraction), one example being the System. out. println() method. We don't know the code that does this work for us, we just know the Method name to use to call it and that is requires one parameter - a String datatype, and that that String is displayed on standard out which is usually the terminal output.

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.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
