An ideal diesel engine has a compression ratio of 20 and uses air as the working fluid. the state of air at 27 c. the maximum temperature in the oycle is the beginning of the compressor process is 100 kpa and 2200 k and the cutoff ratio is 1.2 . determine the internal energies at the beginning and end of compresson

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
