Answer:
Explanation:
Given that velocity=6 m/s
Temperature of surface=75 °C
Temperature of air=25 °C
Reynolds number =
It means that this is laminar flow.So Nusselt equation given as follows
Now properties of air at mean temperature of 75 °C and 25 °C (50 °C) is taken from standard table
K=0.028 W/m-K,Pr=0.71
And we also know that
Now by putting the values
Nu=406.24
So heat flux q= hΔT
q=227.49 x (75-25)
Answer:
The correct answer is "25.03 mm".
Explanation:
Given:
Thickness of plate,
= 10 mm
On a side,
= 100 mm
Diameter hole,
= 25 mm
Coefficient of thermal expansion,
CTE =
Now,
⇒
=
=
=
hence,
The final diameter of hole will be:
A. Double
Piping head loss is calculated by converting all fittings to equivalent length/distance of a specific interior pipe diameter.
Answer:
Honestly overall i think it looks fantastic
Explanation:
It looks like some really nice clean craftsmanship and i love the use of some different colors for some drawers to make it pop. the only con that i can possibly think of is that with it being wood and you moving it from place to place, some rubber feet or something that would prevent it from scratching/damaging anything else if it doesn't already (cant really see under it). other then that one thing i think it looks really good. well done.
Answer: b) False
Explanation: Microscopic energy is the the energy that is based on the molecular level in a particular energy system. Microscopic energy basically comprise with tiny particles like atoms and molecules .The sum of all microscopic form of energy e together make the internal energy .Therefore, the statement given is false because the sum of all the microscopic forms of energy of a system is quantified as internal energy not flow energy.
