Afour-cylinder, four stroke internal combustion engine has a bore of 12 cm and a stoke of 10 cm in each cylinder. the clearance volume is 10% of the cylinder volume at the bottom dead center. the process in each cylinder is modeled as an air-standard otto cycle with a temperature of 300 k and a pressure of 95 kpa at the beginning of compression and the maximum temperature of 1540 k in the cycle. the rate of heat added per unit mass is 750 kj/kg, during the combustion process. assume air to be an ideal gas with variable specific heats. (a) draw the p-v diagram of the modeled otto cycle. label the given temperatures, pressure, and added heat. (b) calculate the network output per unit mass and solve for the thermal efficiency and the mean effective pressure of the cycle

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
