(a) Using Bernoulli's equation, show that be measured fluid speed v for a pitot tube, like the one in figure 14.32(b), is given by v=( 2gh)1/h , where h is be height of be manometer fluid, p' is the density of the manometer fluid, p is the density of the moving fluid, and g is be acceleration due to gravity. (Note that v is indeed proportional to the square root of h, as stated in text) (b) Calculate v for moving air if a mercury manometer's h is 0.200 m. Figure 14.32 Measurement of fluid speed on Bernoulli’s principle. (a) A manometer is connected to two tubes close together and small enough not to disturb the flow. Tube 1 is open at the end facing the flow. A dead spot having zero speed is created there. Tube 2 has an opening on the side, so the fluid has a speed v across; thus, pressure there drops. The difference in pressure at the manometer is 12v22 , so h is proportional to . 12v22 (b) This type of velocity measuring device is a Prandtl tube, also known as a pitot tube.

Problem 2 Assume, your head require 100mmHg or above to function properly. Some tribe had ring extending their neck to some height. If the head is extended to 3 meters. If below 70mmHg at head. you may faint so you should use 100mmHg for calculation. Assuming initial distance between your heart and head is 50cm. Velocity of your blood is 19cm/second at heart. Diameter of vain at heart is 1 inch. Diameter of combined small veins at brain is 10mm. a) Find pressure at heart, flow speed:for 10mm vein at brain if 50 cm height from the heart.
