Answer:
1.62 L
Explanation:
Charle's law for ideal gases states that for a gas kept at constant pressure, the ratio between volume and temperature is constant:

where in this problem we have
is the initial volume of the gas
is the initial temperature of the gas
is the final volume of the gas
is the final temperature
Solving the equation for V2, we find

Explanation:
The given data is as follows.
Fluid is water so, density 
Weight flow rate = 500 lbf/s = 2224.11 N/sec
Cross-sectional area (A) = 
= 0.05184 
Hence, weight flow rate will be given as follows.
w = 
2224.11 N/sec = 
V =
m/s
= 4.373 m/s
Thus, we can conclude that average velocity in the given case is 4.373 m/s.
