If a fluid in laminar flow flows around an obstacle, it exerts a viscous drag on the obstacle.
Frictional forces accelerate the fluid backward (against the direction of flow) and the obstacle forward (in the direction of flow).
The viscous drag force increases linearly with the speed of the fluid.

What two main forces act of a marble while it is falling through oil?
The two main forces acting on a marble falling through oil are gravity, which pulls the marble downward towards the center of the Earth, and drag force, which acts in the opposite direction to slow down the marble's motion as it moves through the viscous fluid of the oil.
Why oil and grease and not water is used in machines as lubricant?
No, water is not lubricant. for example:- if water is spread on ground then we slip then people thinks that water is lubricant but is not the case so the floor is smooth the water is not lubricant. oil and grease are lubricant and they are used in machines.
What is an oil lubricant?
Lubricating oil, sometimes simply called lubricant/lube, is a class of oils used to reduce the friction, heat, and wear between mechanical components that are in contact with each other. ... Mineral lubricating oils are currently the most commonly used type because of the low cost of extracting the oils from crude oil.
What are the properties and applications of viscous oil in industrial processes?
Viscous oil has high resistance to flow and is commonly used in industrial processes such as lubrication, hydraulic systems, and heat transfer. Its properties include high viscosity, which helps reduce friction and wear in machinery, and thermal stability, which allows it to withstand high temperatures. Viscous oil is also used as a sealant and insulator in various applications.
What is the most viscous fraction in crude oil?
The most viscous fraction in crude oil is the residue left over after refining, known as bitumen or heavy oil. It is thick and heavy, with a high viscosity due to its high content of long-chain hydrocarbons.

What is full synthetic and semi synthetic oil?
Oil usually refers to petroleum lubricant. It is refined product of crude oil pumped from underground oil fields around the world. Synthetic oil is lubricant manufactured as a substitute for petroleum lubricant, it was first developed by Germany during WWII to make up their shortages in oil. Semi synthetic oil is a mixture of petroleum lubricant and syntetic lubricant.
What two main forces act of a marble while it is falling through oil?
The two main forces acting on a marble falling through oil are gravity, which pulls the marble downward towards the center of the Earth, and drag force, which acts in the opposite direction to slow down the marble's motion as it moves through the viscous fluid of the oil.

What is the definition of lubricate?

Discuss how effective a car suspension damper would be if the oil in the damper was replaced by oil that was much more viscous?
The effectiveness of a car suspension damper after exchanging the oil in the damper with oil that is much more viscous is increased. The viscous oil gives a smoother and a more powerful effect to the suspension damper.
What is the purpose of checking acid value of lubricant oil?
The purpose of checking the acid value of the lubricant oil is that it determines the efficiency.
Is Ostwalds viscometer used to measure viscosity of more viscous oil?
Yes, the Ostwalds viscometer can be used to measure the viscosity of more viscous oil.
What is the synonym of grease?
lubricant or oil
What are the types of lubricant?
oil and butter
Can a pregnant woman use baby oil as a sexual lubricant?
Yes. She can use baby oil of a reputed company as a sexual lubricant.
