Temperature measurement of compressed air
Temperature measurement of compressed air
(OP)
I am trying to estimate the temperature of compressed air at 7 bar g., stored in a receiver of 1 cubic metre volume. I have measured the surface temperature of the receiver by using a surface temperature probe and thermocouple. The probe was properly covered using insulation during the measurement.
I do not have facility to directly insert a probe into the receiver. I also don't have thermowells on the receiver.
How can I derive a relationship between the receiver surface temperature and the actual air temperature inside? (Assuming there is no airflow into/from the receiver during the measurement).

RE: Temperature measurement of compressed air
Unless the air is high temperature or there is something unusual about your setup, I would not worry about the temperature drop across the inside air film.
