Consider two liquids of densities p₁ = 1000 kg/m³ and p2 = 800 kg/m³ that are initially flowing in pipe1 and pipe2, respectively. The two flow streams are mixed when they merge into the horizontal pipe3 as shown in the figure.

A brine solution of salt flows at a constant rate of 9 L/min into a large tank that initially held 100 L of brine solution in which was dissolved 0.2 kg of salt. The solution inside the tank is kept well stirred and flows out of the tank at the same rate. If the concentration of salt in the brine entering the tank is 0.02 kg/L, determine the mass of salt in the tank after t min. When will the concentration of salt in the tank reach 0.01 kg/L?

One part of an inspection system in a packaging operation uses an air blast to remove defective pieces of cardboard from the conveyor belt. The blast is initiated by a sensor and clocked so that the product is in front of the blast at just the right . The product is going to be dumped onto a shelf next to the conveyor belt. Determine the speed of the air jet required to tip the cardboard off the conveyor. The density of air is 1.10 kg/m3. The cardboard has a mass of 0.10 kg and the jet has a diameter of 10 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.
