Question

Transcribed Image Text:An anaerobic biofuel production process is carried out in a 10,000-L stirred tank
with a diameter of 2 m. In order to ensure proper mixing, agitation will be provided
using a marine propeller at an agitation rate of 100 rpm. Assume the impeller diam-
eter is half of the tank diameter. Note: With a marine impeller, when the impeller
Reynolds number is greater than 3x103, the power number has a value of 1.0. What
is the power of the motor that is required to accomplish this? You can assume the
medium has the properties of water.

The inlet and exit angles of both moving and fixed blades are 40° and 20° respectively, the work done factor is 0.82, six stages for each compressor. intercooling between stages. A high pressure turbine is used to drive the compressors, and a low pressure turbine drives the generator. The temperature of the gases at entry to the high pressure turbine is 600°C and the gases are reheated to 700°C after expansion in the first turbine. The exhaust gases leaving the low pressure turbine are passed through a heat exchanger to heat the air leaving the high pressure stage compressor. The air inlet temperature to the unit is 20°C. The isentropic efficiency of each turbine stage is 0.95; the heat exchanger thermal ratio is 0.7. A mechanical loss is 5% for both the generator- turbine shaft and the compressor- turbine shaft.
