Answer:
b) False
Explanation:
Viscosity:
Viscosity is a fluid property and comes in the picture when fluid in the motion.In Simple words viscosity is the frictional force offered by fluid between the fluid layer.Viscosity provides a resistant to flow of fluid.
Generally viscosity are of two types
1.Dynamics viscosity
2.Kinematics viscosity
Generally in liquids when temperature of fluid is increases then molecular force between fluid particle goes to decreases.Due to this viscosity of liquids will decrease.
So our option b is right.

Explanation:
Thickness of aluminum alloy fin = 12 mm
width = 10 mm
length = 50 mm
Ambient air temperature = 22°C
Temperature of aluminum alloy is maintained at 120°C
<u>a) Determine temperature at end of fin</u>
m = √ hp/Ka
= √( 140*2 ) / ( 12 * 10^-3 * 55 )
= √ 280 / 0.66 = 20.60
Attached below is the remaining answers
Explanation:
1) Wind energy is generated through a wind turbine. When wind passes through the blades of wind mill, the blades of the wind mill tend to rotate. Due to the spinning of the rotor across the turbine, the kinetic energy from the wind is converted to electrical energy
2) Incase of wind energy, the consumption gets higher when there is more wind and would be zero incase of no movement of blades.
Incase of hydroelectric power, the generation is rather stable and consumption depends on the usage of power from the consumers
Incase of gasoline generator, the generation is also stable subject to availability of gasoline and consumption again depends on the usage of power from the consumers
3) Pros of Hydroelectric power
Cost of electricity generation is less
Can produce green energy
Produce mass volume of electricity
Cons of Hydroelectric power
Requires massive initial investement
Can be installed on certain demographical area
Answer:
Explanation:
From the question we are told that:
Water flow Rate 
Initial Temperature 
Final Temperature 
Let
Specific heat of water 
And
Generally the equation for Heat transfer rate of water 
is mathematically given by
Heat transfer rate to water= mass flow rate* specific heat* change in temperature
Therefore
