Before compression, the air in an ideal otto cycle engine is 98 kpa and 17°c. the compression ratio is 8.4, the displacement volume is 2.7l and the temperature after the heat addition process is 2100 k. using variable specific heat analysis, determine: . a)- maximum pressure in the cycle (in kpa) b)- heat input per cycle, in k] c)- net work per cycle, in kj

What precautions should you take to prevent injuries when dealing with heavy loads?

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
