A section of blood vessel wall has become weakened resulting in an increase in the vessel wall diameter of 32%. For this question treat blood as an incompressible non viscous fluid of density 1050 kg m−3. If the vessel normally carries blood at a speed of 1.2 m s−1 then what is the magnitude of the increase in pressure in the bulge in the blood vessel? (to 2 s.f and in Pa)

Water flows at speed of 6 m/s through a horizontal pipe of
diameter 3.5 cm. The gauge pressure P1 of the water in the pipe is
1.7 atm. A short segment of the pipe is constricted to a smaller
diameter of 2.4 cm .
What is the gauge pressure of the water flowing through the
constricted segment? Atmospheric pressure is 1.013 × 10^5 Pa. The
density of water is 1000 kg/m^3 . The viscosity of water is
negligible. Answer in...

The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...

What volume of the water per second can flow through a pipe 5.02 cm in diameter before turbulent flow will occur? Assume that density of the water is 1000 kg/m3 and viscosity of the water 0.972 mPas. Give your answer to two decimal places and you don't have to add unit cm3/s after your numerical value.

While a person is walking, his arms swing through approximately a 45.0 ∘ angle in 0.480 s . As a reasonable approximation, we can assume that the arm moves with constant speed during each swing. A typical arm is 70.0 cm long, measured from the shoulder joint. 1.What is the acceleration (m/s^2) of a 1.70 gram drop of blood in the fingertips at the bottom of the swing? 2. Find the force (N) that the blood vessel must exert on...
