What is the expected pressure reading in the brake pipe (BP) of the front Power Car after holding it at 5.0 Kg/Cm2 for 3 minutes?
Understand the Problem
The question is asking for the expected pressure reading in the brake pipe of a specific vehicle component after it has been held at a certain pressure for a period of time. It implies a mechanical understanding of pressure systems and how pressure readings can change over time.
Answer
Not more than 0.2 kg/cm2 drop from 5.0 kg/cm2 in 3 minutes.
The expected pressure reading in the brake pipe (BP) should not fall more than 0.2 kg/cm2 in 3 minutes from the initial pressure of 5.0 kg/cm2.
Answer for screen readers
The expected pressure reading in the brake pipe (BP) should not fall more than 0.2 kg/cm2 in 3 minutes from the initial pressure of 5.0 kg/cm2.
More Information
Air brake systems are designed to maintain a stable pressure to keep the brakes in a released state, with minimal pressure loss over time.
Tips
Assume the standard operating conditions unless stated otherwise.
