(i) One end of a uniform glass capillary tube of radius r = 0.025 cm is immersed vertically in water to a depth h = 1cm . Contact angle is 0^(@) , surface tension of water is 7.5 × 10–2 N//m , density of water is rho = 10^(3) kg//m^(3) and atmospheric pressure is P_(o) = 10^(5) N // m^(2) Find the excess pressure to be applied on the water in the capillary tube so that - (a) The water level in the tube becomes same as that in the vessel. (b) Is it possible to blow out an air bubble out of the tube by increasing the pressure? (ii) A container contains two immiscible liquids of density rho_(1) and rho_(2) (rho_(2) gt rho_(1)) . A capillary of radius r is inserted in the liquid so that its bottom reaches up to denser liquid and lighter liquid does not enter into the capillary. Denser liquid rises in capillary and attain height equal to h which is also equal to column length of lighter liquid. Assuming zero contact angle find surface tension of the heavier liquid.
The figure shows a crude type of perfume atomizer. When bulb at A is compressed, air flows swifty through the tiny BC with uniform speed v , there by causing a reduced pressure at the position of verticall tube DE . The liquid of density 500kg//m^(3) , then rises in the tube, enters tube BC and sprayed out. When bulb is in natural position the air in the bulb and tube are at atmospheric pressure P_(0=15)^(5)N//m^(2) . When bulb A is compressed, it creates an exces pressure Deltap=0.001P_(0) inside the bulb A . Density of air is 1.3 kg//m^(3) .

A tube of uniform cross section is used to siphon water from a vessel V as shown in the figure. The pressure over the open end of water in the vessel is atmospheric pressure (P_(0)) . The height of the tube above and below the water level in the vessel are h_(1) and h_(2) , respectively. Given h_(1) = h_(2) = 3.0 m , the gauge pressure of water in the highest level CD of the tube will be
