The large tank contains air at an absolute pressure of 700 kPa and temperature of 400 K. The converging nozzle between the tank and the pipe has an exit diameter of 40 mm and the absolute pressure in the pipe is 150 kPa. For air R = 286.9 J/[kg · K] and k = 1.40. (Figure 1) Determine the mass flow from the tank the pipe. Express your answer using three significant figures. m = kg/s
Air (ρa = 0.08 lbm/ft3) flows through a furnace where it is burned with fuel toproduce a hot gas (ρg = 0.05 lbm/ft3) that flows up the stack, as shown in the following figure.The pressures in the gas and the immediately surrounding air at the top of the stack at point Aare equal. What is the difference Δh (in.) in water levels in the manometer connectedbetween the base B of the stack and the outside air at point C? Which side rises? Except forthe pressure drop across the furnace (which you need not worry about), treat the problem asone in hydrostatics. That is, ignore any frictional effects and kinetic energy changes in thestack. Also, you can neglect compressibility effects and assume that the density of gas isconstant.
