Light of wavelength 400 nm and a power of 1.83 x 10-6 w is incident onto a photodetector with quantum efficiency 0.57. the sensor is connected to a 5.7 k52 load resistor and operated at a temperature of 300 k. (a) determine the responsivity of the detector. (b) determine the photocurrent produced by the detector. (c) if the sensor is connected to a 5.7 ks2 load resistor, determine the voltage generated across the load resistor from this photocurrent. (d) if the detector is dominated by johnson noise and has a measurement bandwidth of 1 mhz, estimate the snr.

Atwo-stage air compressor operates at steady state, compression 10m^3/min of air from 100 kpa and 300k to 1200 kpa. an intercooler between the two stages cools the air to 300k at a constant pressure of 350 kpa. the compression processes are isentropic. a) calculate the power required to run the compressor, in kw b) compare the result to the power required for isentropic compression from the same inlet state to the same final pressure.
