Consider a reciprocating engine mechanism OCP shown in Fig, the piston mass at P of the reciprocating parts is accelerating. Thus a primary force is required to accelerate the reciprocating mass. This force acts in a direction...

A reciprocating engine say, an IC engine has both rotating and reciprocating parts. The rotating masses in a single cylinder and a multi cylinder can be balanced using the methods already discussed in the previous chapter. The...
In the following sections, the frequency of transverse vibrations of various systems and the phenomenon of whirling speed have been discussed. Natural Frequency of Free Transverse Vibrations Consider a shaft of negligible mass...
Step 1 : The delivery valve is closed and the suction pipe, casing and portion of the delivery pipe up to the delivery valve are completely filled with the liquid so that no air pocket is left. This process is called priming a...
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 pumps in which a dynamic...
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 piston and the liquid is sucked from the sump...
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. It is usually placed above the liquid level in...
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 cylinder. These pumps usually have...
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 read with the help of...
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 Manometers Simple manometers are used to measure the...
