During blood transfusion the needle is inserted in a veinn where the gauge pressure is 2000 Pa. At what height must the blood container be placed so that blood may just enter the vein? [density of hole blood `=1.06xx10^(3)kgm^(-3)`]
(a). 0.192
(b). 0.182
(c). 0.172
(d). 0.162

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) .

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) .

What is the minimum pressure required to force the blood from the heart to the top of the head (vertical distance 0.5m ) ? [density of blood is 1040 kg m^(-3). Fraction is to be neglected and g=9.8ms^(-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)

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

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?

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.)

What is the pressure drop (in mm Hg) in the blood as it passes through a capillary 1mm long and 2mu m in radius if the speed of the blood through the centre of the capillary is 0.66mm/s ? (The viscosity of whole blood is 4xx10^(-3) PI)
