Hello student, in the first part the diver is submerged at 5 meter below water.
00:08
So, and also we are given that atmospheric pressure equals to 101 ,000 pascal.
00:26
Now, the force on the diver is f1 plus f2 where f1 is the force due to water and f2 is the force due to atmosphere.
00:52
Due to atmosphere.
01:03
So, the absolute pressure at the diver is p1 plus p2 where p1 is the pressure due to water and p2 is the pressure due to atmosphere.
01:18
Now, p1 equals to rho gh where rho is the density of the water which is given as 999 kg per meter cube and g is given as 9 .8 and h is 5 meter.
01:35
So, this will be in the unit of pascal or newton per meter square.
01:39
So, this is equals to 48 ,951 pascal.
01:49
So, the absolute pressure p equals to 48 ,951 plus 101 ,000 pascal.
02:12
So, this is the pressure due to water, this is the pressure due to atmosphere.
02:18
So, which is equals to 149 .95 kilo pascal.
02:27
So, the pressure at the diver is 149 .95 kilo pascal.
02:43
Now, in the next part we have a manometer and pressure at both the ends has to be equal...
