because the deeper one dives the more pressure (from the increasing body of water now pushing down on him and the water around him). This increased pressure can cause rupturing of the ear drum as well as other physiological changes. Another equally detrimental act is returning from a deep dive too quickly. the rapid loss of pressure can cause a diver's blood to form bubbles in it from being in what, in relation to the deep dive, is essentially a vacuum.

It is advised to put some dried neem leaves in an iron drum because the leaves give a smell to the wheat that acts as an insecticide and keeps the pests away from the drum containing wheat.

Na3po4 dosing boiler drum is used mainly for two things. To soften calcium and magnesium to make them slushy and to increase phosphate.
Usually high pressure boiler feed water is a 3 cell control using the drum level transmitters average, Steam flow Transmitter and feed water flow transmitter The drum level controller is tuned so that the drum level is around the half glass depending on load using the steam flow as a feed forward & drum level trim (lifting the drum level above SP under high load and lowering drum level under SP for low load)and the water flow to balance out with the steam flow (mind you if you blow down or have a tube leak the drum level will open the feed water control valve to maintain level) the main tuning in the P.I.D for this is Gain and integral not using derivative as it is too abrupt in its response obviously the actual full control schematics is a lot more complex than this
A diver cannot go too deep at sea without breaking his eardrum because the more deeper you go under the water the more harder the presseure get and your eardrum is justa thin piece of skin and if that breaks you could become deth or you ear might get really infected.
Brake drums can be resurfaced by turning the brake drum in a brake drum lathe. When the brake drum has deep grooves in it, it cannot be repaired.
by breaking it and put parts in it

A bass drum creates a very low and deep sound. The bigger the bass drum, the lower and deeper the pitch.
There are two main Samba drums, The deep booming bass drum is named a Surdo. The slightly more high pitched load drum is called a Tamborim
3-3 is just a song and it cannot be explained literally like a drum.
The ropes are very tightly on the drum so that a system of metal rings bring the skin over the drum shell. Also the drum is hollow so that there would be sound when you hit it and vibrates with the air inside the drum.
