special devices include the thermocouple gauge, the Pirani gauge, the thermistor gauge, the McLeod gauge, and the ionization gauge.

Negative skin friction is basically a shear drag on the pile acting downwards. It causes the pile to sink and subsequent reduction in the load carrying capacity

Ideal fluid is a hypothetical case where there is zero viscocity and the fluid is incompressible. Viscocity is the friction between the different layers of the fluid.

Pressure at every point of an ideal fluid is equal in all directions, whether the fluid is at rest or in motion. A Newtonian fluid is a fluid in which the viscous stresses arising from its flow, at every point, are linearly proportional to the local strain rate.

It is the point where the total sum of a pressure field acts on a body, causing a force to act through that point. The vector sum of all individual forces are expected to pass through the point.

A flow is said to be uniform when the velocity of flow does not change either in magnitude or in direction at any point in a flowing fluid, at a given instant of time.

Flag : The one bit registers provided in microcontrollers to store the results of certain program instructions

Typical drop out voltage across 7805 fixed positive voltage regulator is 2V

Thermistors are generally produced using powdered metal oxides.

Static Pressure. … When measured relative to the atmospheric pressure, the static pressure is the same as the gauge pressure. However, it is possible to measure the static pressure with a vacuum as the reference, so that the value measured equals the absolute pressure.
