A converging nozzle having an exit diameter of 30 mmmm is connected to the large tank (Figure 1). The absolute pressure outside the tank is 102 kPakPa.   Figure 1 of 1   Part A If the temperature of the air in the tank is 20∘C∘C and the absolute pressure is 280 kPakPa, determine the mass flow from the tank.

Air at a temperature of 20°C and standard atmospheric pressure of 102 kPa flows through the nozzle into the pipe where the absolute internal pressure is 60 kPa. The nozzle has a throat diameter of d = 11 mm. (Figure 1) Figure 1 of 1 Part A Determine the mass flow into the pipe. Express your answer using three significant figures.

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.

The large tank contains air at an absolute pressure of 80 psi and temperature of 70°F. The nozzle has a throat diameter of 1 in. and an exit diameter of 1.75 in. (Figure 1) Part A T = °R. Part B Determine the absolute pressure within the connected pipe so that the nozzle chokes, but also maintains isentropic subsonic flow within the divergent section of the nozzle. Express your answer using three significant figures. p = psi Part C Determine the mass flow into the tank if the absolute pressure within the pipe is 30 psi. Express your answer using three significant figures. m = slug/s

Problem 2 - Determine the greatest possible mass flow through the nozzle if the throat has a diameter of 50 mm. The air in the reservoir has an absolute pressure of 400 kPa and a temperature of 30°C. I mm

A medical syringe (shown below) is used to inject a patient with a local anaesthetic before performing outpatient surgery. The anaesthetic can be modeled as an incompressible fluid with specific gravity, S = 1.02. Determine the plunger velocity, in units of in/s, if the anaesthetic is to be delivered at a constant 7 cm3 s −1 when the syringe is modeled as being perfectly sealed, and there is backward leakage between the plunger and syringe at a rate of 10% of the volume flow rate delivered through the needle. Note that anaesthetic is still to be delivered to the patient at 7 cm3 s −1 , despite this leakage.

The large cylindrical tank contains air at an absolute pressure of 200 psi and temperature of 90°F. The throat of the nozzle has a diameter of 0.25 in., and the exit diameter is 0.75 in. (Figure 1) Part A Determine the absolute pressure in the pipe required to choke the nozzle and also maintain isentropic subsonic flow through the pipe. Express your answer using four significant figures. p= psi Part B What is the velocity of the flow through the pipe for this condition? Express your answer to three significant figures and include the appropriate units. V = Value Units

An airplane is in level flight at low altitude, so that atmospheric pressure and densities are 1 atm and 1 kg/m3, respectively. There is a Pitot tube attached to the airplane, so that air entering the tube stagnates at the rear of the tube. The stagnation pressure is measured to be 1.45 x 105PA. What is the speed of the airplane?
