What is the length of the liquid column in a barometer tube that would support an
atmospheric pressure of 102000 Nm-3 if the
density of the liquid is 2600 kgm-3?
(g = 10ms-2)
​

For this case we must convert 26 seconds to hours,

By definition we have to:

1 hour equals 3600 seconds.

So, if we propose a rule of three we have:

1 hour ----------> 3600 seconds

x ------------------> 26 seconds

Where the variable "x" represents the number of hours equivalent to 26 seconds:

Thus, 26 seconds equals approximately 0.0072 hours.

0.0072 hours
