A torpedo fired from a submerged submarine is propelled through the water
with a speed of 20.00 m/s and explodes upon impact with a target 2000.0 m
away. If the sound of the impact is heard 101.4 s after the torpedo was fired,
what is the speed of sound in water? (Because the torpedo is held at a constant
speed by its propeller, the effect of water resistance can be neglected.)

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.
