A manometer is an device employed to measure pressure. There are a variety of manometer designs. A simple‚ common design is to seal a length of glass tubing and bend the glass tube into a U-shape. The glass tube is then filled with a liquid‚ typically mercury‚ so that all trapped air is removed from the sealed end of the tube. The glass tube is then positioned with the curved region at the bottom. The mercury settles to the bottom After the mercury settles to the bottom of the manometer‚ a vacuum

chemical weathering and biological weathering. Physical weathering- is the breaking down of rocks into smaller fragments brought about by physical (mechanical) forces. Works through 4 processes: alternate expansion and contraction‚ frost action‚ pressure release and salt crystal growth. Alternate expansion and contraction- this process occurs in areas such as desserts. The rock expands during the day because of the heat and contracts at night when temperatures drop below freezing point (0 degrees)

pressurization of the inside of the aircraft to a higher level than outside the aircraft‚ this is done by taking air from the ram stage of the gas turbine. This air is then supplied to the heat exchanger at minimum pressure. When the aircraft is in flight‚ the air is bled from the low pressure stage of the compressor‚ this supplies air to the aircrafts pneumatic systems. But when the aircraft is on the ground at a standstill‚ there is no pressurization in the gas turbine. The high

diameter d = 3500mm and 5km long is used to pump water. An obstruction plugs the pipe at an unknown location so that no liquid can flow. A piston is placed in one end of the pipe and slides (without leakage)‚ compressing the water in the pipe. The pressure increases 855 k Pa when the piston is moved a distance of 734mm into the pipe. If the temperature of the liquid =300 C‚ how far down the pipe would you estimate the obstruction to be? 3- Derive an expression for the capillary height change h for
