Salt water brine (10 % nacl by weight) with a viscosity of 0.0016 (n s)/m2 and a thermal conductivity of 0.85 w/(m k) is flowing through a long, 2.5 cm inside diameter pipe at 3 m/s. for an initial brine temperature of -1°c and a constant pipe surface temperature of 18.3°c, determine the temperature rise of the brine over the first meter of pipe. assume that the specific heat of the brine is 3768 j/(kg k) and that its density is 1077 kg/m3

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
