Blood flow in the body proceeds in pulses, so it might happen that turbulence will occur only during the high-speed phase of each pulse. Assume the diameter of the aorta is 2.5 cm2.5 cm. Take 1050 kg/m31050 kg/m3 as the density of blood and 2.084×10–3Pa as its viscosity. a. Calculate the critical volume flow rate at which turbulence is a certainty in the aorta, assuming a Reynolds number of 3000 is guaranteed to correspond to a turbulent flow. Give your answer in liters per minute.

A water tank of constant depth H, open to the atmosphere, is connected to the piping system, as shown in Figure P8.45. After a length of pipe L of diameter D, the diameter decreases smoothly to a value of D/2 and then continues on for another length L before exiting to atmosphere. The flow is turbulent and the friction factor f is the same for all piping. CD1 and CD2 are the loss coefficients for the entry and exit. Calculate the depth of the tank required to produce a mean exit velocity of V .  

The pressure drop along a length of artery is 103 Pa, the radius is 9.5 mm, and the flow is laminar. The average speed of the blood is 16.5 mm/s.Randomized Variables P = 103 Par = 9.5 mms = 16.5 mm/s a. What is the net force on the blood in this section of artery in N?  b. What is the power expended maintaining the flow in mW?

True or false E Hydraulic jump is a rapidly varied flow. L The specific energy is the energy at a cross-section of an open channel flow with respect to any arbitrary datum. At critical depth, the specific energy is maximum. A 2 m wide concrete rectangular channel with a roughness (n) of 0.012, a slope of 0.2 % and with water depth of 1 m, the estimated flow rate in the channel is 950 m/s. Specific Force curve is the relationship between the specific force and the conjugate water depths The critical flow condition corresponds to the maximum specific discharge in a channel for a fixed specific energy. Open-channel flows are characterized by the presence of a liquid-gas interface called the free surface. I In open-channel flow, the depth of flow, discharge and the slopes of channel bottom and of the free surface are dependent variables. A channel built with the same cross section and bottom slope is called a PRISMATIC CHANNEL. Channel section, which is composed, of different roughness…
