1.What is the volumetric flow rate of a solution with density 1.5 kg/m3 flowing at a velocity of 5 m/s and a mass flow rate of 500 g/min? What is the area of the pipe? If it is circular, what is the radius?

2.Suppose that a river with a molar flow rate of 10000 mol/s meets another, larger river flowing at 500000 m3/s at room temperature. What is the mass flow rate of the river downstream of the intersection if you assume steady state? Evaluate the feasibility of the steady state assumption in this situation.

Methane is flowing in a pipeline at a target rate of 20.7 m3/min at 30°C and 250 kPa. To check the flow rate, He is introduced at 25°C and 300 kPa. How many cubic centimeters per minute of He must be added if the minimum detectable concentration of He downstream of the injection point is 10 ppm? I dont understand what "minimum detectable concentration of He downstream of the injection point" means?

One method to determine the flow rate of a turbulently flowing stream is to inject a small, metered amount of some easily dispersed fluid and then to measure the concentration of this fluid in a sample of the mixed stream withdrawn a suitable distance downstream. In pharmaceutical plants, there are often many inert gas streams (i.e., streams that contain mostly nonreacting gases). In a particular plant, there is a process stream that is composed of 95mol% N2(inert) and 5 mol%...

Ethanol with a density of 789 kg/m3 moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is P1 = 1.90 ✕ 10^4 Pa, and the pipe diameter is 8.00 cm. At another point y = 0.40 m higher, the pressure is P2 = 1.05 ✕ 10^4 Pa and the pipe diameter is 4.00 cm. A tube is open at both its left and right ends. The tube starts at...

Consider a 20 * 105 m3 lake fed by a polluted stream having a flow rate of 4.2 m3/s and pollutant concentration equal to 25 mg/L. There is also a sewage outfall that discharges 0.5 m3/s of wastewater having a pollutant concentration of 275 mg/L. The stream and sewage wastes have a second order decay rate of 0.32/day. Assuming the pollutant is completely mixed in the lake and assuming no evaporation or other water losses or gains, find the steady-state...
