Afour-cylinder, four-stroke internal combustion engine operates at 2800 rpm. the processes within each cylinder are modeled on cold air-standard otto cycle with a pressure of 14.7 lbf/in.2 , a temperature of 80of, and a volume of 0.0196 ft3 at the beginning of compression. the compression ratio is 10, and maximum pressure in the cycle is 1080 lbf/in.2 determine, using a cold air-standard analysis, the power developed by the engine, in horsepower, and the mean effective pressure, in lbf/in.2

answer:

ask me the quest

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
