(a) For a nonsmoker, with blood viscosity of 2.50 x 103 pa-s, normal blood flow requires a pressure difference of 8 mm Hg between the two ends of a certain artery. If this person were to smoke regularly, his blood viscosity could increase to 2.83 x 10 Pa-s (a 13% increase), and the diameter of his artery would constrict by 10%. What pressure difference between the ends of the artery would then be needed to maintain the same blood flow rate? mm of Hg (b) Which had a larger effect on the pressure difference needed: the change in viscosity, or the change in the diameter of the artery?

Description: Smoking tobacco is bad for your circulatory health. In an attempt to maintain the blood's capacity to deliver oxygen, the body increases its red blood cell production, and this increases the viscosity of the blood. In addition, nicotine from tobacco

The gravitational force exerted on a solid object is 5.00 N. When the object is suspended from a spring scale and submerged in water, the scale reads 3.50 N (Fig. P15.24). Find the density of the object. Figure P15.24 Problems 24 and 25.
A horizontal pipe 10.0 cm in diameter has a smooth reduction to a pipe 5.00 cm in diameter. If the pressure of the water in the larger pipe is 8.00 104 Pa and the pressure in the smaller pipe is 6.00 104 Pa, at what rate does water flow through the pipes?
How tall must a water-filled manometer be to measure blood pressures as high as 300 mm Hg?
Two thin-walled drinking glasses having equal base areas but different shapes, with very different cross-sectional areas above the base, are filled to the same level with water. According to the expression P = P0 + gh, the pressure is the same at the bottom of both glasses. In view of this equality, why does one weigh more than the other?
How tall must be to measure blood pressure as high as 300 mm Hg?
If the pressure in the esophagus is -2.00 mm Hg while that in the stomach is +20.0 mm Hg, to what height could stomach fluid rise in the esophagus, assuming a density of 1.10 g/mL? (This movement will not occur if the muscle closing the lower end of the esophagus is working properly.)
An incompressible, nonviscous fluid is initially at rest in the vertical portion of the pipe shown in Figure P15.61a, where L = 2.00 m. When the valve is opened, the fluid flows into the horizontal section of the pipe. What is the fluids speed when all the fluid is in the horizontal section as shown in Figure P15.61b? Assume the cross-sectional area of the entire pipe is constant. Figure P15.61
