During blood transfusion the needle is inserted in a vein where the gauge pressure is `2000Pa` . At what height must the blood container be placed so that blood may just enter the vein? Density of whole blood = `1.06xx10^(3)Kg//m^(3)`.

Text Solution

Verified by Experts

`h=P//rhog=200//(1.06xx10^(3)xx9.8)=0.1925m`
The blood may just enter the vein if the height at which the gblood container be kept must be slightly greater than `0.1925m` i.e., 0.2m.

The flow of blood in a large artery of an anaeshetized dog is diverted throg]ugh a venturimeter. The wider part of the meter has a cross sectional area equal to that of the artery i.e. 8 mm^(2) . The narrower parts has an are 4 mm^(2) . The pressure dorp in the artery is 24Pa . what is the speed of the blood in the artery ? Given that density of the blood = 1.06 xx 10^(3) kg//m^(3)

The flow of blood in a large artery of a anesthetized dog is diverted through a venturimeter. The wider part of the meter has a cross-sectional area equal to that of the artery. Ie., 10mm^(2) . The narrower part has an area 5 mm^(2) . The pressure drop in the artery is 22 Pa . Density of the blood pressure drop in the artery is 22Pa . Density of the blood pressure drop in the artery is 22Pa . Density of the blood is 1.06xx10^(3)kgm^(-3) . The speed of the blood in the artery is

Calculate the hydrostatic difference in blood pressure between the brain and the foot in a person of height 1.50 m. The density of blood is 1.06 xx 10^(3) kg//m^(3) .

Giraffe bending to drink. In a giraffe with its head 1.8 m above its heart, and its heart 2.0 m above its feet, the (hydrostatic) gauge pressure in the blood at its heart is 250 torr. Assume that the giraffe stands upright and the blood density is 1.06 xx 10^(3) kg// m^(3) . In torr (or mm Hg), find the (gauge) blood pressure (a) at the brain (the pressure is enough to perfuse the brain with blood, to keep the giraffe from fainting) and (b) at the feet (the pressure must be countered by tight-fitting skin acting like a pressure stocking). (c) If the giraffe were to lower its head to drink from a pond without splaying its legs and moving slowly, what would be the increase in the blood pressure in the brain? (Such action would probably be lethal.)

A glass tube of 1 mm bore is dipped vertically into a container of mercury, with its lower end 5 cm below the mercury surface. What must be the gauge pressure of air in the tube to a hemispherical bubble at its lower end? Given density of mercury = 13.6 xx 10^(3) kg//m^(3) , surface tension of mercury = 440 xx 10^(-3) Nm^(-1) and g = 10m//s^(2)

The human heart discharges 75ml of blood at each beat against a pressure of 0.1m of Hg. Calculate the power of the heart assuming that the pulse frequency is 80 beats per minute. Given, density of mercury =13.6xx10^(3) kg//m^(3)

Blood pressure in Argentinosaurus. (a) If this long-necked, gigantic sauropod had a head height of 18 m and a heart height of 8.0 m, what (hydrostatic) gauge pressure in its blood was required at the heart such that the blood pressure at the brain was 80 torr (just enough to perfuse the brain with blood)? Assume the blood had a density of 1.06 xx 10 kg//m^(3) . (b) What was the blood pressure (in torr or mm Hg) at the feet?
