Viscosity: Resistance of a fluid (liquid or gas) to a change in shape, or movement of neighboring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow.

A psychrometer measures the relative humidity in the atmosphere through the use of two thermometers: a dry bulb thermometer, is used to measure the temperature by being exposed to the air. a wet bulb thermometer, measures temperature by having the bulb dipped in a liquid.

A process variable, process value or process parameter is the current measured value of a particular part of a process which is being monitored or controlled. The current temperature is called the process variable, while the desired temperature is known as the set-point

In adiabatic process, No heat transfer takes place hence Q=0

As per first law of thermodynamics,
Q=W?U

reduces to

W = -?U

Morse test is used to find the power produced inside an individual engine cylinder , which also called Indicated Power(IP)

It can also be used to find frictional power lost in an engine cylinder.

Indicated Power = Brake Power ??? Power

Second law of thermodynamics is based on Kelvin-Planck statement , which is about conversion of heat into work and vice versa .

When a survey line is longer than a chain length, it is necessary to align intermediate points on chain line so that the measurements are along the line. The process of locating intermediate points on survey line is known as ranging.

By Height of instrument method

Height of instrument(H.I) = reduced level (R.L) backsight (B.S)

or H.I = R.L – F.S

at point A

R.L = 100.000
B.S = 1.100
H.I = 100.000 1.100 = 101.100
at point B
B.S = 1.000
H.I = 101.100
R.L = 101.100 – 1.000 = 100.100
therefore reduced level at B = 100.100

Out of the given choices , a passive network cannot provide greater power.

AC always produce alternating voltage and current. Since capacitive circuit, it produces charging current in positive half cycle and discharging current in negative half cycle.
