Centrifugal pumps are the devices which convert the mechanical energy into hydraulic energy by means of centrifugal force acting on the fluid. Centrifugal pumps are classified as roto dynamic type of...

In a double acting reciprocating pump, the suction and delivery strokes occur simultaneously. When the crank rotates from IDC to ODC, a vacuum is created on the left side of the...

In a single acting reciprocating pumps, liquid acts on one side of the piston only. Image shows a single acting reciprocating pump which has one suction pipe and one delivery pipe....

The reciprocating pumps is a positive displacement pump. It operates on the principle of actual displacement or pushing the liquid by a piston or plunger that reciprocates in a closely fitting...

There are two methods of dimensional analysis used. Rayleigh's method Buckingham π-Theorem Rayleigh's Method In Rayleigh's method, the expression is determined for a variable depending upon maximum three or four variables only. If...

One dimensional flow is the type of flow in which the flow characteristics such as velocity, pressure, density, temperature etc. are the function of time and one space co-ordinate only. Mathematically, u=f(x) ;...

Most of the conventional pressure gauges are of a mechanical type. These gauges embody on elastic element which deflects under the action of the applied pressure. This movement mechanically magnified and...

Manometers is the device which is used for measuring the pressure at a point in a fluid by balancing the column of fluid by the same or another column of liquid. Simple...

The surface tension is due to cohesion between particles at the free surface. Due to molecular attraction, liquids have properties of cohesion and adhesion. Cohesion is due to the force of...

Fluid may be defined as a substance which is capable of flowing. It has no definite shape of its own but it confirms the shape of the containing vessel. A small...
