Answer:
The volume of the extra water is 
Solution:
As per the question:
Mass of the canoe, 
Height of the canoe, h = 21.5 ft
Mass of the kevlar canoe, 
Now, we know that, bouyant force equals the weight of the fluid displaced:
Now,
(1)
where
V = volume
= density
m = mass
Now, for the canoe,
Using eqn (1):
Similarly, for Kevlar canoe:
Now, for the excess volume:
V = 
V = 
Answer:
16.38L
Explanation:
Through laboratory tests, thermodynamic tables were developed, these allow to know all the thermodynamic properties of a substance (entropy, enthalpy, pressure, specific volume, internal energy etc ..)
through prior knowledge of two other properties.
Quality is defined as the ratio between the amount of steam and liquid when a fluid is in a state of saturation, this means that since the quality is 50%, 1kg is liquid and 1kg is steam.
then to solve this problem we find the specific volume for ammonia in a saturated liquid state at 20C, and multiply it by mass (1kg)
v(amonia at 20C)=0.001638m^3/kg
m=(0.01638)(1)=0.01638m^3=16.38L
