5. A sample stream of dry gas is being withdrawn from a stack. The stack gases are at 200 °C and 730 mmHg. The stream flows through a heated filter, a set of cooled impingers, a small air pump, and them through a flow meter, as shown in Figure 1. The rate of flow is determined to be 30.0 liters/min at 20 °C and 790 mm Hg. a) Calculate the actual volumetric flow rate through the filter (at T = 200 °C and P = 730 mmHg). b) If 1.42 mg of solid particles are collected on the filter in 30 minutes, calculate the concentration of particles in the stack gas (in mg/m³)

A jet of water having a velocity of 45 m/s impinges without shock on a series of vanes moving at 15 m/s. The direction of motion of the vanes is inclined at 20° to that of the jet, the relative velocity at outlet is 0.9 of that at inlet, and the absolute velocity of the water at exits is to be normal to the motion of vanes.

Air passes through a narrow section during horizontal flow. The initial air temperature is 21 [℃], flow rate 91.5 [m / s], pressure 10.56 [Kg / cm2 abs], later flow rate 152 [m/s], pressure 7.05 [Kg/cm2. abs], what is the temperature of the air at the outlet if there is no outside or heat coming in?

In oasis Water Company to purify the water, it is flowing through a reducer in a horizontal pipe where the diameter is reduced from 35 cm to 25 cm. The pressure in the 35 cm pipe just upstream of the reducer is 3 150 kPa. The fluid has a vapor pressure of 50 kPa and a specific weight of 5 kN/m . Neglecting frictional effects, calculate flow rate of water through this pipe in lit/s. Draw diagram neatly.
In mixing tanks systems, the water comes in at a rate of 4L/min in Tank A. This tank contains 500L solution of brine with 200g of salt is dissolved. The solution is then pumped to Tanks B and C, at 2L/min and X L/min, respectively. Tank B has 400L solution of brine and 1000g dissolved salt. It is then pumped to Tank C with a rate of 4L/min. Tank C has only 400L of plain water only and pumps it back to Tank B at a rate of y L/min. Moreover, z L/min exits the system of Tank C. Considering that the volume of the solutions are constant all throughout, solve for the values of x, y, z

Suppose that you are willing to determine the diameter of the water jet impinging to the sink from the kitchen tap.The tap is produced to supply three different flow rates of the low, medium, and high. For each flow rate level, waterthat comes from the tap fills the beaker with a volume of 30 mL in 10 s, 6 s, and 2 s, respectively. The outlet of the tapis 13 mm, and the distance between the tap outlet and the sink is 53 mm. Determine the diameters of the water jetimpinging on the sink at three given flow rates.
