Problem 8.85

Air at 1 atm and 285 K enters a 2-m-long rectangular duct with cross section 75 mm 150 mm. The duct is maintained at a constant surface temperature of 400 K, and the air mass flow rate is 0.10 kg/s. Determine the heat transfer rate from the duct to the air and the air outlet temperature

Step-by-Step Solution:
Step 1 of 3

Lecture 11: Fluids/Thermodynamics Outcomes  Explain the different pressures and calculate o Atmospheric pressure o Absolute pressure o Gauge pressure o Hydrostatic pressure o Vacuum pressure Pressure  Normal force exerted per unit area by a fluid  Where o P = pressure (scalar) o F = normal force (vector) o A = area (vector!)  SI units: N/m = Pascal [Pa]  US: lb fin = psi  Also bar, mm Hg, in Hg, torr (see unit conversion sheet) Pressure Example 1 Pressure - Types & Relationships  Atmospheric [P atm - pressure exerted at a certain location o Standard atmospheric pressure =  1 atm (at sea level)
