Question 68Motor Plants - Assistant Engineer

The correct answer is A) The output of "2" will always be less than the input at "1" by 0.35 bar. This is correct because the circuit shown in the illustration depicts a pressure-reducing valve, which is a device used to reduce the pressure of a fluid or gas from a higher inlet pressure to a lower, controlled outlet pressure. The pressure drop across the valve is typically around 0.35 bar, meaning the output pressure at "2" will be approximately 0.35 bar less than the input pressure at "1". The other answer choices are incorrect because they do not accurately describe the operation of a pressure-reducing valve. Choice B, C, and D do not provide the correct relationship between the input and output pressures of the circuit.
