Consider a bathtub, in which both the tap as well as the drainage are open. If the tap is set to 0.1

kg/s of mass flow rate, while the drainage capacity is 0.08 kg/s, then the net rate of outflow from the

bathtub is:

Consider a water hose, from which a jet of water exits as shown in Fig. 3. The pressure inside the

water jet – in terms of gauge pressure - just after leaving the hose (i.e. at point A) will be:

Figure 1 below shows a pipe of length L, (with L >>D) and with viscous flow inside. The flow is fully developed

at the exit plane. The velocity distribution at the inlet is uniform. At the exit plane, only the shape of the velocity

distribution is illustrated: the magnitudes are not to scale. What should be the magnitude of the maximum

velocity at the centerline of the exit plane, v_2,max?

When solving fluid flow problems with the Linear Momentum theorem, the force terms calculated

correspond to:

From the theories listed below, which application requires the setup of a Control Volume?

After graduation, you get your dream job as an Aerodynamicist at one of the Indycar teams. Your

task is to calculate the pressure at a point over the front wing of the racecar. If the top speed of the

racecar is 300 km/h, then can you use the Bernoulli equation to calculate the pressure? (You may

assume that the racecar is exposed to standard sea-level conditions, where the speed of sound is 340

m/s).

Q1. The continuity law is based on the conservation of:

If we record the x – y coordinates of a cork floating over the river surface (where the x-y plane

coincides with the river surface), at a location where the flow direction is varying with time, then we

essentially have recorded the:

Incompressible fluid means that:

The Pitot tube is used to measure:
