A closed, rigid tank is filled with water. Initially, the tank holds 9.9 ft3 of saturated vapor and 0.1 ft3 of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. For the water, determine (a) the quality at the initial state, (b) the temperature at the final state, in °F, and (c) the heat transfer, in Btu. Kinetic and potential energy effects can be ignored.

a) x₁ = 0.058

b) T₂ = 416.02°F

c) q = 5047.39 Btu

Explanation:

see the attached file

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
