Physics Problems: Pipe and Water Speed
Welcome to our physics session! We appreciate your presence and
we hope that you'll enjoy this learning experience. Before we
proceed, we encourage our online viewers to like and share this
session as your support motivates us to continue providing free
educational contents. Let's start with a problem:
1. A pipe with diameter d is connected to another pipe with n holes,
each having a diameter of d. If the speed of the water in the first
pipe is E, what is the speed of the water in the second pipe in terms
of n, d, and capital E?
Take your time to think about the problem and check your answer.
We assure you that we will cover all the concepts in physics in our
sessions. Don't forget to like and share the session for more updates

Important Physics Questions and Concepts
Good morning Aditya! Let's get started by covering some important
questions and concepts in physics that may get directly or indirectly
repeated on the exam. By mastering these questions, you will have
a better chance of scoring 50+ in physics.

get started by looking at some of the important questions from past
exams. We had Sanskrit 1250 - let's see if you can answer the next
two questions.
Free Exam Preparation: Important Concepts
and Equations
, We are providing important concepts and equations for free, which
are frequently repeated in competitive exams like BITSET, mains,
advance, and music. It is crucial to find the relation between the
given and asked and try to complete the question. Let's answer the
following question:
Question 1
A uniform chain of length l is lying on a horizontal table, and the
coefficient of friction between the chain and the table is mu. What is
the maximum length of chain that can hang over the edge of the
table without disturbing the rest of the chain?
To write the maximum length that can be hanged in terms of l and
mu: mu * l / mu = l.
Answer the question and comment your answers below.
Similar concepts are frequently repeated, and you can expect 15 to
20 marks in the exam. Share this session to benefit others.
Question 2
What is the total kinetic energy in case two?
Write the equation for the moment of inertia for a hollow sphere:
Hollow sphere: 2/3 * m * r^2
The moment of inertia of a hollow spherical body is represented by i
which is equal to 2/3mr². In this scenario, both the sphere and water
are moving in translation motion, so we cannot take ms²m as water
is not rotating but moving in a straight line. Thus, the final answer is
2m.
For the first question, the answer is 99.37 degrees Celsius or 372
degrees Fahrenheit.
If you want to find the efficiency, use the formula 1 - t2/t1 which is
given as 1/6. Thus, the efficiency is one-sixth as the first reversible
