Exhaust gases from a manufacturing plant are being discharged through a 10-m-tall exhaust stack with outer diameter of 1.2 m. The exhaust gases are discharged at a rate of 1.2 kg/s, while temperature drop between inlet and exit of the exhaust stack is 30°C, and the constant pressure specific heat of the exhaust gasses is 1600 J/kg·K. On a particular day, wind at 27°C is blowing across the exhaust stack with a velocity of 10 m/s, while the outer surface...

Air (Cp = 1.005 kJ/kg · K) is to be preheated by hot exhaust gases in a cross-flow heat exchanger before it enters the furnace. Air enters the heat exchanger at 95 kPa and 20◦C at a rate of 0.90 kg/s. The combustion gases (Cp = 1.1 kJ/kg · K) enter at a rate of 1.1 kg/s and 150◦C. The product of the overall heat transfer coefficient and the heat transfer surface area is U A = 1200 W/K. Assuming...

A thin film having an index of refraction of 1.50 is surrounded by air. It is illuminated normally by white light. Analysis of the reflected light shows that the wavelengths 360, 450, and 600 nm are the only missing wavelengths in the visible portion of the spectrum. That is, for those wavelengths, there is destructive interference. (a) What is the thickness of the film? nm (b) What wavelengths in the visible portion of the spectrum are brightest in the reflected...

Air flows through a heating duct with a square cross-section with 5-inch sides at a speed of 5.3 ft/s. Just before reaching an outlet in the floor of a room, the duct widens to assume a square cross-section with sides equal to 13 inches. Compute the speed of the air flowing into the room (in ft/s), assuming that we can treat the air as an incompressible fluid. Answer should be in Ft/s

A thin-walled air ionization chamber whose volume is 0.5cm^3 collects a charge of 1.65 x 10^ -9 C when placed into a plastic phantom whose relative mass stopping power is 1.1. When manufactured, the ionization chamber was sealed when the temperature was 25 degrees C and the atmospheric pressure was 770 mm Hg. What was the absorbed dose, in Gy and in rads, at the point of measurement?
