Manometer is used to measure
A. pressure in pipes, channels etc
B. atmospheric pressure
C. very low pressure
D. difference of pressure between two points
Answer: Option A
Solution (By Examveda Team)
Manometers are devices in which columns of a suitable liquid are used to measure the difference in pressure between two points or between a certain point and the atmosphere. The manometer is needed for measuring large gauge pressures.This Question Belongs to Civil Engineering >> Hydraulics And Fluid Mechanics

A. 22.5 m/sec.
B. 33 m/sec.
C. 40 m/sec.
D. 90 m/sec.
A. the weight of the body
B. more than the weight of the body
C. less than the weight of the body
D. weight of the fluid displaced by the body
The difference of pressure between the inside and outside of a liquid drop is
A. $${\text{p}} = {\text{T}} \times {\text{r}}$$
B. $${\text{p}} = \frac{{\text{T}}}{{\text{r}}}$$
C. $${\text{p}} = \frac{{\text{T}}}{{2{\text{r}}}}$$
D. $${\text{p}} = \frac{{2{\text{T}}}}{{\text{r}}}$$
A. cannot be subjected to shear forces
B. always expands until it fills any container
C. has the same shear stress.at a point regardless of its motion
D. cannot remain at rest under action of any shear force
Option A is correct
It simply says manometer otherwise if it would have been said about differential manometer then option d was correct so satisfied with b option
Manometers are defined as the devices used for measuring the pressure at a point in a fluid by balancing the column of fluid by same or another column
Differential manometers gives the difference of pressure between two points in a fluid in same pipe or in different
Plzz don't make fool the students
option D is CORRECT
