Question B1 - Compression Before entering the engine of a BMW320D, air drawn in at 20°C and atmospheric pressure enters the compressor of a turbocharger at a rate of 120 litres per minute. The inlet pipe to the compressor has an internal diameter of 18 mm, the outlet pipe of the compressor has an internal diameter of 26 mm and is axially aligned with the inlet pipe. The compressor raises the pressure and temperature of the exiting air to 4 bar (absolute) and 161°C. a) Determine the density of the air into and out of the compressor. b) Calculate the mass flow rate of air through the compressor. c) Determine the inlet and outlet velocity of air in to and out of the compressor.

Transcribed Image Text:Question B1 - Compression
Before entering the engine of a BMW320D, air drawn in at 20°C and atmospheric
pressure enters the compressor of a turbocharger at a rate of 120 litres per minute.
The inlet pipe to the compressor has an internal diameter of 18 mm, the outlet pipe
of the compressor has an internal diameter of 26 mm and is axially aligned with the
inlet pipe. The compressor raises the pressure and temperature of the exiting air to
4 bar (absolute) and 161°C.
a)
Determine the density of the air into and out of the compressor.
b)
Calculate the mass flow rate of air through the compressor.
c)
Determine the inlet and outlet velocity of air in to and out of the compressor.
