Step 1
First, we need to use the polyfit command in Matlab to obtain the best curve fit for air velocity V as a function of voltage E. We can do this by typing the following command in the Matlab command window: coeffs = polyfit(E, ns, n) where E is the HWA output Show more…

The air velocity in the duct of a heating system is to be measured by a Pitot-static probe inserted into the duct parallel to the flow. If the differential height between the water columns connected to the two outlets of the probe is 2.4 cm, determine (a) the flow velocity and (b) the pressure rise at the tip of the probe. The air temperature and pressure in the duct are 45°C and 98 kPa, respectively.

Air enters a rectangular duct measuring 30 cm x 40 cm with a velocity of 8.5 m/s and a temperature of 40°C. The flowing air has a thermal conductivity of 0.028 W/m-deg, kinematic viscosity of 16.95 x 10^-6 m^2/s, and from empirical correlations, the Nusselt number has been approximated to be 425. Work out the equivalent diameter of the flow passage, the flow Reynolds number, and the convective heat flow coefficient.
