A 1.5 m3 tank contains 500 kg of liquid water in equilibrium with pure water vapor, which fills the remainder of the tank. The t
emperature and pressure are 100°C and 101.33 kPa. From a water line at a constant temperature of 70°C and a constant pres- sure somewhat above 101.33 kPa, 750 kg of liquid is bled into the tank. If the temper- ature and pressure in the tank are not to change as a result of the process, how much energy as heat must be transferred to the tank?

Answer:
(a) Acceleration of the bag will be a=16.214m/sec^2
(B) Weight of the bag will be 137.2 N
Explanation:
We have given mass of the bag m = 14 kg
Force with which bag is lifted = 227 N
(A) According to newtons law we force is equal to F = ma , here m is mass and a is acceleration
So
(b) Acceleration due to gravity
We know that weight is given by W = mg , here m is mass and g is acceleration due to gravity
So weight
So weight of the bag will be 137.2 N
