By sucking through a straw, a student can reduce the pressure in his lungs to 750 mm of Hg(density `13.6 gcm^(-3))` using the straw, he can drink water from a glass up to a maximum depth of

A

10 cm

B

75 cm

C

`13.6` cm

D

`1.36 cm`

Text Solution

Verified by Experts

The correct Answer is:
C
Pressure difference between lungs and atmosphere =760 mm-750 mm =10 mm 1 cm of Hg.
Pressuire difference `=1xx13.6xxg=lxxlxxg ` of water.
i.e. one can drawn a depth of `13.6` cm of water

By sucking a straw a student can reduce the pressure in his lungs to 750 mm of Hg ("density")= 13.6 kg//cm^(3)) Using the straw, he can drink water from a glass up to a maximum depth of :

The spouting can is something used to demonstrate the variation fo pressure with depth. When the corks are removed from the tubes in the side of the can, water flows out with a speed that depends on the depth. In a certain can, three tubes T_(1),T_(2) and T_(3) are set at equal distance 'a' above the base of the can. When water contained in this can is allowed to came out of hte tubes, the distance on the horizontal surface are measured as x_(1),x_(2) and x_(3) . Distance x_(3) is given by

When an object moves through a fluid, as when a ball falls through air or a glass sphere falls through water te fluid exerts a viscous foce F on the object this force tends to slow the object for a small sphere of radius r moving is given by stoke's law, F_(w)=6pietarv . in this formula eta in the coefficient of viscosity of the fluid which is the proportionality constant that determines how much tangential force is required to move a fluid layer at a constant speed v, when the layer has an area A and is located a perpendicular distance z from and immobile surface. the magnitude of the force is given by F=etaAv//z . For a viscous fluid to move from location 2 to location 1 along 2 must exceed that at location 1, poiseuilles's law given the volumes flow rate Q that results from such a pressure difference P_(2)-P_(1) . The flow rate of expressed by the formula Q=(piR^(4)(P_(2)-P_(1)))/(8etaL) poiseuille's law remains valid as long as the fluid flow is laminar. For a sfficiently high speed however the flow becomes turbulent flow is laminar as long as the reynolds number is less than approximately 2000. This number is given by the formula R_(e)=(2overline(v)rhoR)/(eta) In which overline(v) is the average speed rho is the density eta is the coefficient of viscosity of the fluid and R is the radius of the pipe. Take the density of water to be rho=1000kg//m^(3) Q. What is the viscous force on a glass sphere of radius r=1mm falling through water (eta=1xx10^(-3)Pa-s) when the sphere has speed of 3m/s?
