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

ABC is a light pipe lying in a vertical plane and of cross sectional area 1 cm^(2) whose small part is in ground to fix the pipe. An ideal fluid of density 10 ^(4) kg//m^(3) is being flown through the pipe by means of external agency. Length of BC can be neglected. The minimum vertical upward force required to pull out the pipe from ground is F=9N . What should be maximum velocity (in m//s ) of the fluid so that pipe can not be pulled out from ground ?
