That statement is incorrect!
The claim is untrue
Answer:
B) P1 would have to increase to sustain the flow rate (correct)
C) Resistance would rise (correct)
Explanation:
Flow rate is measured at 10 liters per minute
Driving pressure (P1) stands at 20 cm H2O
Fixed downstream pressure (P2) is 5 cm H2O
The accurate statements when the lumen is pinched in the center of the tube are: P1 will increase to maintain the flow rate, and resistance will rise. This occurs because pinching the lumen decreases its diameter, leading to higher resistance, which is linearly related to pressure, thus P1 will also increase.
The incorrect statement is: the flow would decrease.
An item of protective gear that shields individuals passing by from stray sparks or metal during the welding process performed by another worker is known as: E. Welding Screens.
An operator is a person tasked with joining two or more metals using a technique called wielding.
In the course of wielding, both sparks and tiny metallic fragments are released, which pose a danger to the operator and others working nearby.
As a result, the equipment outlined below should be worn or utilized directly by a worker actuating the wielding process:
Nonetheless, a type of protective gear that defends other workers nearby from stray sparks or metallic fragments while the operator (worker) is in the act of welding is called welding screens.
