An aircraft carrier is moving at a speed of 44 knots when the propeller shafts are instantaneously stopped. if the speed reduces to 20 knots in 24 minutes determine and plot the distance (s) in nautical miles the ship travels and the speed (v) during this time interval. the deceleration of the ship is proportional to the square of the speed; i. e. a=-kv^2?

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
