Two gaseous stream containing the same fluid enter a mixing chamber and leave as a single stream. For the first gas the entrance condition are A1 = 500 cm2 , υ1 = 300 m/sec, ρ1 = 1.60 kg/m3 . For the second gas the entrance conditions are A2 = 400 cm2 , m2 = 8.84 kg/sec, v2 = 0.502 m3 /kg. The exit stream condition is υ3 = 130 m/s and v3 = 0.437 m3 /kg. Determine (a) the velocity of gas 2 (b) the area at the exit section in cm2 .

Q4. Water from a reservoir is conveyed via a pipeline of constant diameter and 1000m length to a turbine situated 90m below the reservoir surface level. The velocity of flow through the pipeline is 5m/s and the energy loss due to friction in the pipeline is 200J/kg. The water leaves the turbine at atmospheric pressure (100 kN/m2) and with negligible velocity. Assuming an efficiency of 85% for the turbine, determine: a). Pipeline diameter b). Pressure at entry to turbine c). Turbine power output. Take f = 0.025

Air (assumed incompressible) flows steadily into the square inlet of an air scoop with the nonuniform velocity profile indicated in Figure. The air exits as a uniform flow through a round pipe 1 ft in diameter. (a) Determine the average velocity at the exit plane. (b) In one minute, how many pounds of air pass through the scoop

A large, open-topped water tank is being filled from above by a 1.0-cm-diameter hose. The water in the hose has a uniform speed of 11 cm/s. Meanwhile, the tank springs a leak at the bottom. The hole has a diameter of 0.70 cm. Determine the equilibrium level heq of the water in the tank, O measured relative to the bottom, if water continues flowing into the tank at the same rate. heq 1.26 X10-3 Incorrect m

We would like to calculate the minimum pressure required to force plasma from the heart to the top of the head. For this analysis we will assume blood is a Newtonian, incompressible fluid. The distance from the heart to the top of the head is 0.5m. Assume the density of plasma to be 1065 kg/m3. The vein diameter is 0.95 mm. Assume friction can be neglected.
