Oil is carried through pipes from one place to another place. It is made sure that the flow of
oil in pipes should be steady so that there is no danger of the damage of the pipe. Assume that an
oil flows through a horizontal pipe of length 2.0 m and radius 50 cm. The amount of the oil
collected at one end of the pipe is 5.0 x 10⁻³ kg/s. Assume that density of oil is 0.5 x 10³ kg/m³
and coefficient of viscosity of oil at 30 °C is 0.02 Pa-s.
Based on the above facts, answer the following questions
(A)The volume of the oil flowing per second is
a) 1x 10⁻⁶ m³ /s
b) 1x 10⁻⁵ m³ /s
c) 1x10⁻⁴ m³ /s
d) 1 m³ /s
(B) The velocity of flow of oil in the pipe is
a) 1.0 x 10⁻⁵ m/s
b) 1.3 x 10⁻⁵ m/s
c) 2.0 x 10⁻⁵ m/s
d) 2.3 x 10⁻⁵ m/s
(C) Pressure difference between the ends of the pipe is
a) 1.63 x 10⁻⁵ Pa
b) 2.63 x 10⁻⁵ Pa
c) 4 x 10⁻⁶ Pa
d) 6 x 10⁻⁶ Pa
(D) Reynolds number is
a) 0.00163
b) 0.0163
c) 0.163

(E) Flow of oil in the pipe is
a) laminar
b) turbulent
c) unstable
d) laminar as well as turbulent
Do not litter on the road or in your neighbourhood. Littering causes land, air and water pollution. Try planting trees and plants that will beautify our surroundings as well as keep us healthy. Greener surroundings look beautiful and also reduce pollution to keep us fit and healthy
Activities like advertisement, marketing, and sales promotion initiates the customer to buy the product or service from a company and thus leads to to increase in sales. Production is a process of manufacturing readymade product which is to be sold in the market and thus will not help with lead generation.

Accounting principles should be FLEXIBLE enough and not so rigid.
Explanation:
Accounting is a man-made law made for the smooth sailing of various businesses. It goes without saying that if do not update the laws we follow we can never grow and make our lives better. Hence, the Flexibility Principle states that the accounting system need to shape itself according to the needs and demands of the company. Not only it helps with fast pace of work but also provides the reporting managers with oppurtunities to give a proper judgement in areas of monetary transactions.
