1. Elasticity is___________
a) Breakage
b) Reversible deformation
c) Irreversible deformation
d) Liquid
Discussion
Explanation: Elasticity is reversible deformation. Reversible deformation can be defined as a state when a matter is reverted to the original form after stress is removed.
2. Deformation force can be ______________
a) Static
b) Dynamic
c) Static and dynamic
d) Short
Discussion
Explanation: The deformation forces which act on a solid body or a liquid can be Static: the force is acting constantly and its direction and magnitude are constant and dynamic: the magnitude and/or direction of the force(s) are variable as a function of time.
3. Viscosity varied ________ with temperature and _______ with fat content of milk.
a) Linearly and exponentially
b) Exponentially and linearly
c) Exponentially and exponentially
d) Linearly and linearly
Discussion
Explanation: Viscosity varies exponentially with temperature and linearly with a fat content of milk. Viscosity for the fat and temperature range measured varied from 1-60 centipoises.
4. The rate at which milk flows through a closed pipe can be determined by _____________
a) Determining the mass flow rate
b) Determining the volume flow rate
c) Mass flow rate and volume flow rate
d) Fat content
Discussion
Explanation: Flow rate determines the flow rate of milk through a closed pipe. Volume flow rate also plays a major role in determining the flow rate.
5.Conveyor-based methods are used for the measurement of the flow of _____________
a) Solids
b) Liquid
c) Gas
d) Gel
Discussion
Explanation: Conveyor-based method determines flow of solids. Liquid, gas. Gel flow characteristic cannot be determined by this method
6. For the measurement of flow rate of liquid, the method used is _____________
a) Conveyor-based methods
b) Bourdon tube
c) Coriolis method
d) Thermal mass flow measurement
Discussion
Explanation: Using the Coriolis Effect that causes a laterally vibrating tube to distort, a direct measurement of mass flow can be obtained in a coriolis flow meter. Hence, coriolis method is used for the measuring liquid flow rate.
7. The device cannot be used for flow obstruction is _____________
a) Orifice plate
b) Venturi tube
c) Flow nozzle and dall flow tube
d) sphere
Discussion
Explanation: Orifice plate, venture tube and flow nozzle all these devices are used for flow obstruction. Sphere can’t be used for flow obstruction.
8. The device which is used for making temporary measurements of flow is _____________
a) Venturi
b) Dull flow tube
c) Orifice plate
d) Pitot static tube
Discussion
Explanation: An orifice plate is a device used for measuring flow rate, for reducing pressure or for restricting flow. It is also used to make temporary flow measurements
9. For the measurement of flow, the cheapest device is _____________
a) Venturi
b) Dall flow tube
c) Flow nozzle
d) Pitot static tube
Discussion
Explanation: Flow nozzle is the most economical device for the measurement of flow. Dall flow tube, Venturi and Pitot static tube are comparatively expensive.
10. The instrument which is not suitable for the application in an automatic control scheme is _____________
a) Rotameters
b) Pitot static tube
c) Rotary piston meter
d) Orifice plate
Discussion
Explanation: In rotameter, the falling and rising action of a float in a tapered tube provide a measure of flow rateRotameter is not suitable in the automatic control scheme.
