Nitrogen flows steadily through a converging tube. Near the inlet, the nitrogen is at 8.0 psia, 40 °F with a density of 0.0423 lbm/ft3 and has a velocity of 1600 ft/s through a cross sectional area of 0.40 sq. ft. At a section farther stream, the calculated density is 0.0225 lbm/ft3 and velocity is 1 300 ft/s. Determine the cross section at the downstream section.
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 3.2 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
The fluid condition at the inlet and exit of a horizontal convergent nozzle is analysed. The nozzle is operating steadily and heat loss is assumed negligible. If the specific enthalpy of fluid and velocity of fluid at the inlet are 3,314 kJ/kg and 226 km/hr respectively. At the exit the specific enthalpy of fluid is 2,563 J/kg. Calculate the exit area (in mm-)of the nozzle when the specific volume at the nozzle exit is 0.61 m3/kg at the inlet area of 0.23 m2 and the specific volume at the inlet is 0.3 m3/kg.
Carbon dioxide flows steadily through a varying cross- sectional-area duct such as a nozzle at a mass flow rate of 3 kg/s. The carbon dioxide enters the duct at a pressure of 1400 kPa and 200°C with a low velocity, and it expands in the nozzle to a pressure of 200 kPa. The duct is designed so that the flow can be approximated as isentropic. Determine the following parameters at each location along the duct that corresponds to a pressure drop of 200 kPa: (i) density; (ii) velocity: (iii) flow area; (iv) mach number. You may assume: • Carbon dioxide is an ideal gas with constant specific heats at room temperature; • Flow through the duct is steady, one-dimensional and isentropic. Use c, 0 846 kJ/kgk andk = 1.289 throughout the calculations, which are the constant-pressure specific heat and specific heat ratio values of carbon dioxide at room temperature. The gas constant of carbon dioxide is R = 0.1889 kJ/kg K.

An iron bar 2.0 cm x 3.0 cm x 10.0 cm at a temperature of 95 °C is dropped into a barrel of water at 25 °C. The barrel is large enough so that the water temperature rises negligibly as the bar cools. The rate at which heat is transferred from the bar to the water is given by the expression Q (J/min) = UA (Th - Tw.) where U = 0.05 J/(min cm °C)] is a (cm) is the exposed surface area of the bar, T₁, and T are the surface temperature of the bar and the water temperature, respectively. The heat capacity of the bar is 0.46 J/(g °C).
