MICRO MANOMETERS AND INCLINED MANOMETER Introduction Micro-manometers and inclined manometers are modified forms of simple U-tube manometer. Micro-Manometer Micro-manometer is also known as single column manometers. The construction of a micro-manometer is as follows: One limb of manometer is a tank of large cross sectional area as compared to the cross sectional area of the other limb. This tank acts as a reservoir to hold the manometer fluid. The cross sectional area of the tank is 100 times greater than that of the other limb. When there is change in the pressure in the pipe, there is negligible change in the level of fluid in tank.  This change can be neglected and pressure can be measured as height of liquid in the other column. It is of two types: i.   Vertical column micro-manometer ii.   Inclined column micro-manometer 1.Vertical Column Micro-manometer Initially, when there is no fluid flowing in the pipe the level of manometer liquid is at XX. But due to liquid p...

SIMPLE MANOMETER, PIEZOMETER, U-TUBE MANOMETER   Introduction There are many techniques for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges. Manometers are used for the measurement of very low pressures as well as vacuum especially in hydraulic laboratories. Manometers Manometers are used for measuring pressures by balancing the fluid column of fluid against another column of fluid of known specific gravity.  Manometers can be classified as: 1.   Simple manometers a. Piezometer b. U-tube manometer 2.   Micro manometers (or single column manometers) a. Vertical column micro manometer b.   Inclined column micro manometer 3.   Differential manometers a. Upright U-tube differential manometer b. Inverted   U -tube differential manometer 1.  Simple manometers It consists of a glass tube with one end open to the atmosphere and other end connected to a point at which pressure is to be measured. a. Pi...

  COMPRESSIBLE AND NON COMPRESSIBLE FLUIDS, SURFACE TENSION AND CAPILLARITY Compressible and Non Compressible Fluids 1. Compressible fluids:  The fluids which undergoes a change in volume or density when subjected to external forces. 2. Incompressible fluids: The fluid which does not show a change in volume or density when subjected to external forces. Compressibility It is the property of the liquid or fluid due to which there will be a change in volume/density when the fluid is subjected to an external force and is represented by Bulk Modulus of Elasticity (k).  Compressibility is the reciprocal of Bulk Modulus of Elasticity. Ideal Fluids are incompressible. Real Fluids are compressible.   Numericals Q.1  Change in pressure for a liquid is 2 MN/m 2 . The volumetric strain induced in the liquid was 0.05. Determine the bulk modulus of elasticity for the liquid. =4x10^7 N/m2 Q.2  A cylinder having 10 litre  volume  is completely filled with oil. Wh...

STATIC PRESSURE OF LIQUIDS , HYDRAULIC PRESSURE, ABSOLUTE AND GAUGE PRESSURE: Numerical Q1. A hydraulic press has a diameter ratio between the two  piston  of 8:1. The diameter of the larger piston is 600 mm and it is required to support a mass of 3500 kg. The press filled with hydraulic fluid of  sp.gravity  0.8. Calculate the force required on the smaller piston to provide the required force: a)  When  the two pistons are at the same level. B) When the smaller piston is 2.6 m below the larger piston . Solution.                                                                     F2=536.48N F2=625.94N Q2. The diameter of the piston of a hydraulic jack is 6 times greater than the diameter of the plunger which is 200 mm. They are both at same ...
