Blood flows through a 100 μm diameter glass tube that is 0.1 cm in length. Estimate the volumetric flow rate of the blood in cm3 h−1 if the pressure difference over the length of the tube is 6000 Pa.
Blood flows through a 100 μm diameter glass tube that is 0.1 cm in length. Estimate...
Blood is flowing at a flow rate of 7 L/min through a tube that is 6mm in diameter and 50 cm in length. Estimate the pressure drop of the blood over this length of tubing in mmHg.
2. Blood with a hematocrit of 45% flows through a 10 micrometer diameter tube. Flow is directly proportional to the pressure difference across the tube and inversely proportional to the apparent viscosity of blood. Compare the actual pressure difference across the tube with the pressure difference necessary to provide the same flow if the apparent viscosity in the tube remained the same as the apparent viscosity in a very large tube. Discuss implications of the Fahraeus-Lindqvist effect on the work...
Water flows through a horizontal tube of diameter 2.6 cm that is joined to a second horizontal tube of diameter 1.1 cm. The pressure difference between the tubes is 7.7 kPa. Find the speed of flow in the first tube.
4.) Air flows through a 5 cm diameter tube with a speed vo 2 m/s and pressure Po 2 atm. The tube narrows to a diameter of 1 cm. A tube, partially filled with water, connects the wide and narrow sections. 1.2 kg/m The density of air is p h water (a.) What is the air speed in the narrow tube, vi? (b.)

Water flows through a horizontal tube of diameter 2.0 cm that is joined to a second horizontal tube of diameter 1.0 cm. The pressure difference between the tubes is 15 kPa. The density of water is 1000 kg/m. Treat the water as an ideal fluid. Find the speed of flow in the first tube. 1.41 m/s 1.73 m/s 2.00 m/s 1.00 m/s
6: (a) Use the scaling laws to estimate the change of volumetric flow and pressure drop per unit length in a circular tube if the radius of the tube is reduced by a factor of 10. The pressure drop in a capillary tube is given by AP- 8uVavg.Lia. Here, L length of tube, a is the radius, g is the average speed of fluid and u is the viscosity). (b) Evaluate the resistance per unit length (R/L) for water flow...
Instructions The tube shown has a length of 2.00 m and a diameter of 1.00 mm. Water at 40° C is flowing through the tube. For water at 40°C:n=0.7x10-3 A) What pressure difference is required to give the water a flow speed of 4.0 m/s? (Give your answer in units of Pa.) B) What force applied to the end of the tube will produce this pressure? (Give your answer in units of N.) C) What is the volume flow rate...
Fluid originally flows through a tube at a rate of 130 cm3/s. To illustrate the sensitivity of flow rate to various factors, calculate the new flow rate (in cm3/s) for the following changes with all other factors remaining the same as in the original conditions. (a) Pressure difference increases by a factor of 1.30. cm3/s (b) A new fluid with 3.00 times greater viscosity is substituted. cm3/s (c) The tube is replaced by one having 4.00 times the length. cm3/s...
Water flows through a Venturi meter with a pipe diameter of 10.0 cm and a constriction diameter of 5.6 cm. The U-tube manometer is partially filled with mercury. Find the flow rate of the water in the pipe of 10.0 cm diameter if the difference in the mercury level in the U-tube is 3.0 cm. Answer in L/s
An artificial kidney uses porous hollow fibers to purify blood. Blood containing urea flows through the fibers and urea diffuses out, through the porous fiber wall. Tens of thousands of such fibers were used in an artificial kidney. We would like to determing the fraction of the urea removed as blood flows through one such fiber. The fiber has a radius of R = 100 µm and length L = 10 cm. The flow rate of blood (viscosity 0.03 g/cm/s...
