You will be observing laminar-turbulent transition for room temperature (about 20°C) water flowing in a 0.602"" ID pipe (Schedul
e 40 1/2"" pipe). Estimate the flow rate in gallons/minute (gpm) at which transition should begin (ReD= 2300) and the flow rate for fully turbulent flow (ReD> 4000). Repeat calculations for a 0.804"" ID pipe (Schedule 40 3/4"" pipe).

Answer:
Equilibrium Temperature is 382.71 K
Total entropy is 0.228 kJ/K
Solution:
As per the question:
Mass of the Aluminium block, M = 28 kg
Initial temperature of aluminium, = 273 + 140 = 413 K
Mass of Iron block, m = 36 kg
Temperature for iron block, = 273 + 60 = 333 K
At 400 k
Specific heat of Aluminium,
At room temperature
Specific heat of iron,
Now,
To calculate the final equilibrium temperature:
Amount of heat loss by Aluminium = Amount of heat gain by Iron
Thus
= 273 + 109.71 = 382.71 K
where
= Equilibrium temperature
Now,
To calculate the changer in entropy:
Now,
For Aluminium:
For Iron:
Thus
