To Calculate:The net forcethatwill be exerted on a front door to a house and its direction.
Answer to Problem 4PP
Directed from inside of the house outward.
Explanation of Solution
Given data:
Height of a door,
Width of a door,
The pressure drops by
Formula used:
A force (per unit area) that acts on any object is defined by pressure. Force to calculate pressure difference of a particular area, formula is
Calculation:
The pressure difference across the door is
Here,
Thus, the exerted force is directed from inside of the house outward.
Conclusion:
The force
