Cavitation is more pronounced in rough pipes than smooth surfaced pipes.
For liquid fluids will capillarity rise (or fall) increase or decrease with rise in temperature.
Capillarity fall is reduced if we take the appartus (capillary tube immersed in fluid having acute angle of contact) considerable distance inside the earth( i.e below the earth crust).
