JUPEB Physics Past Questions.

Introduction

Welcome to this JUPEB Physics past questions tutorial. In this lesson, we examine an important question on pressure measurement in fluids — a common topic in JUPEB Physics examinations. Understanding which instruments are used for measuring different types of pressure is crucial for solving practical and theoretical questions in fluid mechanics.

Let’s get started with the questions and answers.

Question 1: Measuring Pressure of a Confined Fluid

Question:
The pressure of a confined fluid is measured reliably by which of the following devices?

Options:
A) Manometer and Mercury Barometer
B) Thermometer and Mercury Barometer
C) Hydrometer and Manometer
D) Barometer and Spectrometer

Correct Answer

A) Manometer and Mercury Barometer

Explanation

• A manometer is used for measuring pressure in closed systems, such as confined gases or liquids.
• A mercury barometer is used for measuring atmospheric pressure, which is important for reference or calibration.
• The other instruments — thermometer, hydrometer, and spectrometer — do not measure fluid pressure, making them incorrect for this question.

Hence, the correct combination for measuring confined fluid pressure is manometer and mercury barometer.

Conclusion

Understanding the instruments used to measure pressure in fluids is fundamental in JUPEB Physics examinations, especially in topics like fluid mechanics and hydrostatics. Questions on manometers, barometers, and related instruments are common in past JUPEB papers and often test candidates’ ability to distinguish between tools used for confined pressure, atmospheric pressure, and density measurements.

By consistently practicing past JUPEB Physics questions and mastering the purpose of each instrument, students can improve both their speed and accuracy, ensuring higher scores in this section of the exam.
