The arrangement shown is to be used to calibrate a heat flux gage. The gage has a black surface that is 10 mm in diameter and is maintained at 17C by means of a water-cooled backing plate. The heater, 200 mm in diameter, has a black surface that is maintained at 800 K and is located 0.5 m from the gage. The surroundings and the air are at 27C and the convection heat transfer coefficient between the gage and the air is 15 W/m2 K. (a) Determine the net radiation exchange between the heater and the gage. (b) Determine the net transfer of radiation to the gage per unit area of the gage. (c) What is the net heat transfer rate to the gage per unit area of the gage? (d) If the gage is constructed according to the description of 3.107, what heat flux will it indicate?
STA3032 MODULE 3 ARTICLE I. 3.1 INFERENCE FOR ONE POPULATION 1) When a population parameter is estimated by a sample statistic, this sample estimate is not 100% representative of the population because it varies from sample to sample. 3.1.1 CONFIDENCE INTERVALS 1) Confidence Interval (CI): reports an interval of plausible values based on the point estimate sample statistic and its standard deviation a. To calculate a confidence interval you first i. Select the confidence level 100(1-α)% ii. If the sample is replicated many times, the proportion of times that the CI will not cont
