Modes of heat transfer include conduction, convection, and radiation.

• Conduction: Heat transfer through direct contact between particles or objects.

• Convection: Heat transfer through the movement of fluids or gases.

• Radiation: Heat transfer through electromagnetic waves.

• Examples: Cooking on a stove (conduction), heating a room with a radiator (convection), feeling the warmth of the sun (radiation).

Various types of pumps include centrifugal, positive displacement, axial flow, and jet pumps.

• Centrifugal pumps use a rotating impeller to create a flow of fluid.

• Positive displacement pumps move fluid by trapping a fixed amount and forcing it through the discharge port.

• Axial flow pumps move fluid parallel to the pump shaft.

• Jet pumps use a combination of pressure and suction to move fluid.

• Other types of pumps include gea

The least count of vernier caliper is the smallest measurement that can be read on the scale.

• The least count is determined by the number of divisions on the vernier scale and the main scale.

• It is usually 0.1 mm or 0.02 mm for metric vernier calipers and 0.001 inch for imperial vernier calipers.

• To determine the least count, subtract the value of one main scale division from the value of one vernier scale division.

• For ex...read more

Micrometer screw gauge is used for higher precision measurements than vernier caliper.

• Micrometer screw gauge has a higher accuracy of measurement than vernier caliper.

• Micrometer screw gauge has a smaller least count than vernier caliper.

• Micrometer screw gauge is used for measuring thickness, diameter, and depth of objects with high precision.

• Vernier caliper is used for measuring length, width, and height of objects wit
