PIEZOMETER IS USED FOR MEASUREMENT OF SMALL PRESSURE BUT NOT FOR VARIATION.....SO 1 SHOULD BE WRONG

Question:

Consider the following statements:

1. Piezometer is used to measure small variation of pressure above or below ambient pressure.

2. Thixotropic fluid exhibits decrease in viscosity with time.

Which of these statements is/are correct?

Options:
A)

1 only 

B)

2 only

C)

Both 1 and 2 

D)

Neither 1 nor 2

Solution:

Ans: (c)

Thixotropic fluid are thick fluid under normal condition, but fluid become thin/less viscous over time when shaken, agitated or otherwise stressed.

  

This type of piezometer can be used to measure negative gauge pressure.
