Answer:
The Reynolds number for ethyl alcohol is 91,510
Explanation:
Reynolds number (Re) = density×velocity×diameter/viscosity
density of ethyl alcohol = 789kg/m^3, velocity = 5m/s, diameter = 1 in = 0.0254m, viscosity of ethyl alcohol = 0.001095Pa.s
Re = 789×5×0.0254/0.001095 = 91,510
Answer:
name=input("Enter a name: ")
names = name.split()
if
(len(names)==3): middle=names[1] mid=middle[0].upper()+"." last=names[2]+"," first=names[0] print('Formatted Name:',last,first,mid) elif(len(names)==2): last=names[1]+',' first=names[0]
print('Formatted Name:',last,first)
else:
print('The input does not have the correct form')
Answer:
exergy = 33.39 kW
Explanation:
given data
thermal energy reservoir T2 = 1500 K
heat at a rate = 150,000 kJ/h = kW = 41.67 kW
environment temperature T1 = 25°C = 298 K
solution
we get here maximum efficiency that is reversible efficiency is express as
reversible efficiency = 1 - ...............1
reversible efficiency = 1 -
reversible efficiency = 0.80133
and
the exergy of this supplied energy that is
exergy = efficiency × hat supply ................2
exergy = 0.80133 × 41.67 kW
exergy = 33.39 kW
