A U-tube manometer with one arm open to atmosphere is used to measure the pressure of kerosene vapour passing in a pipe. Mercury used gives height of the column in the arm open to atmosphere greater than 10 cm of mercury level in the arm connected to kerosene pipe. There is a condensation of kerosene vapour on mercury column of 5.1 cm height. If the atmospheric pressure is 75.5 cm of mercury, find the absolute pressure in kPa. Assume specific gravity of kerosene as 0.8 and that of mercury as 13.6.

A U-tube containing mercury (sg = 13.6) has itsright-hand limb open to the atmosphere and the left-handlimb connected to a pipe conveying water under pressure,the difference in the level of mercury in the two limbs being200 mm. If the mercury level in the left-hand limb is 400 mmbelow the pipe's center line, find the pipeline's absolutepressure (kPa). Also, find the new difference in levels ofmercury in the U-tube if the pressure in the pipe falls by 2kPa.

I've posted the below question earlier, and I received the answer. This is the question: A J-shaped tube is filled with air at 760 Torr and 22 °C. The long arm is closed off at the top and is 100.0 cm long; the short arm is 40.00 cm high. Mercury is poured through a funnel into the open end. When the mercury spills over the top of the short arm, what is the pressure on the trapped air? Let h be the length of mercury in the long arm. I need further explanation of one step: - when P2 is obtained in the short arm, the equation is 40-h+P1 1. How did we get this equation? 2. the short arm does not contain any air, why do we create an equation of P2 in the short arm? Please clarify these concerns.

Find the vacuum pressure in pipe, if the difference of mercury level in the two limbs is 40cm and the height of fluid in the left from the center of pipe is 15 cm below.
We have seen in class that water spontaneously rises up when putin contact with a hydrophilic tube. A similar phenomenon occurs when water is put in contact with two parallel hydrophilic plates (Fig. 2). Given that the gap between the plates b = 100 µm, the width of the plates L = 20 cm, and the contact angle between the water and the plates is θ = 5 degrees, find the height of the capillary rise h.
