In one cycle, a freezer uses 780J of electrical energy in order to remove 1730J of heat from its freezer compartment at 10.0 oF.
Part A What is the coefficient of performance of this freezer?
Part B How much heat does it expel into the room during this cycle?
The odd cycle sequences1,3,5,7, and repeats. An external input selects which cycle to perform. An input of 0 selects the even cycle and an input of 1selects the odd cycle. The cycles can be entered and exited throughstates 0 and 1.
A gasoline engine has a power output of 185kW (about 248hp ). Its thermal efficiency is 28.5%. How much heat is discarded by the engine per second
The primary focus of this mini-proposal is the methods and expected conclusions. Emphasis should be placed on clear definition of the phenomena to be investigated, referenced procedures and methods for the investigation, and detailed description of t..
