A scuba diver descends to a depth of 20m. At that depth, thepressure is approximately A)atmospheric pressure.
B)twice atmospheric pressure.
C)three times atmospheric pressure.
D)four times atmospheric pressure.
Hint:
P = P0 + rho*g*h Do not forget P0, the atmosphericpressure.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
