A siphon in use is demonstrated in the following figure. The density of the liquid flowing in siphon is $ 1.5 gm/cc. $ The pressure difference between the point $P$ and $S$ will be
Figures below show water flowing through a horizontal pipe from left to right. Note that the pipe in the middle is narrower. Choose the most appropriate depiction of water levels in the vertical pipes.
The three water filled tanks shown have the same volume and height. If small identical holes are punched near this bottom, which one will be the first to get empty.
Two drops of the same radius are falling through air with a steady velocity of $5 cm per sec.$ If the two drops coalesce, the terminal velocity would be
Water coming out of the mouth of a tap and falling vertically in streamline flow forms a tapering column, i.e., the area of cross-section of the liquid column decreases as it moves down. Which of the following is the most accurate explanation for this
In making an alloy, a substance of specific gravity ${s_1}$ and mass ${m_1}$ is mixed with another substance of specific gravity ${s_2}$ and mass ${m_2}$; then the specific gravity of the alloy is
During blood transfusion the needle is inserted in a vein where the gauge pressure is $2000 \;Pa$. At what height (in $m$) must the blood container be placed so that blood may just enter the vein ?
Density of whole blood, $\rho=1.06 \times 10^{3} \;kg m ^{-3}$
