Answer:
(a) Frequency induced voltage of motor is 120 Hz
(b) The speed at which the machine will produce an average torque is 240π rad/s. Maximum Torque is 1.0 Nm
Explanation:
Answer:
Q=0.00274 Lt/s
Explanation:
Given that
Darcy friction factor f=0.04
Diameter of pipe d=10 mm
We know that for laminar flow
Where Re is the Reynolds number and f is the friction factor.
Now by putting the values
Re=400
We know that
for water
V=0.035 m/s
So volume flow rate Q=AV
Q=0.00274 Lt/s
Answer:
Basically there are two principal differences between the convection and conduction heat transfer
Explanation:
The conduction heat transfer is referred to the transfer between two solids due a temperature difference, while for, the convective heat transfer is referred to the transfer between a fluid (liquid or gas) and a solid. Also, they used different coefficients for its calculation.
We can include on the explanation that conduction thermal transfer is due to temperature difference, while convection thermal transfer is due to density difference.
Answer: Outside an intersections
Explanation:
Answer:
month = input("Input the month (e.g. January, February etc.): ")
day = int(input("Input the day: "))
if month in ('January', 'February', 'March'):
season = 'winter'
elif month in ('April', 'May', 'June'):
season = 'spring'
elif month in ('July', 'August', 'September'):
season = 'summer'
else:
season = 'autumn'
if (month == 'March') and (day > 19):
season = 'spring'
elif (month == 'June') and (day > 20):
season = 'summer'
elif (month == 'September') and (day > 21):
season = 'autumn'
elif (month == 'December') and (day > 20):
season = 'winter'
print("Season is",season)
