Answer:
1.The velocity of fluid
2.Fluid properties.
3.Projected area of object(geometry of the object).
Explanation:
Drag force:
Drag force is a frictional force which offered by fluid when a object is moving in it.Drag force try to oppose the motion of object when object is moving in a medium.
Drag force given as
So we can say that drag force depends on following properties
1.The velocity of fluid
2.Fluid properties.
3.Projected area of object(geometry of the object).
Answer:

Explanation:
The average heat Flux which sometimes can be called heat flux density, heat flow rate intensity or heat-flow density refers to the flow of energy per unit of area per unit of time. the units in SI are computed as watts per square metre . It has both a magnitude as well as a direction and so it is a vector quantity.
The full step by step explanation to the question above can be seen in the attached image below.
Answer:
Explanation:
Given that
a=3.524 A
At.Wt. ,M= 58.7 g/mole,
For FCC
Z = 4
The density given as
So the density is
Answer:
thread depth = 2.5 mm
thread width = 2.5 mm
mean diameter = 27.5 mm
root diameter = 25 mm
lead of screw = 5 mm
Explanation:
given data
power screw diameter D = 30 mm
thread pitch P = 5 mm
solution
First, we get here thread depth fr square thread
thread depth = ......................1
thread depth =
thread depth = 2.5 mm
and
thread width for square thread
thread width = ......................2
thread width =
thread width = 2.5 mm
and
mean diameter is
mean diameter = D - ................3
mean diameter = 30 -
mean diameter = 27.5 mm
and
root diameter is
root diameter = D - P ....................4
root diameter = 30 - 5
root diameter = 25 mm
and
lead of screw for single thread so n = 1
so lead of screw = 1 × 5
lead of screw = 5 mm
