Mechanical Engineering
Mechanical Engineering is a branch of engineering that encompasses the generation and application of heat and mechanical power and the design, production, and use of machines and tools. Mechanical engineering involves application of the principles of dynamics, control, thermodynamics and heat transfer, fluid mechanics, strength of materials, materials science, electronics, and mathematics.

What is the impact factor of International Journal of Modern Engineering Research journal?
less then 1
Why pelton turbine is called as impulse turbine?
Water is blasted at the buckets one by one or more jets mounted in the surroundings casing. Momentum is transferred from water to buckets and a torque is created, causing the wheel to rotate. That's why it is an impulse turbine.
Which types of screw threads are used in railway carriage couplings?
knuckle threads are used in railway carriage couplings.
jubo
What happens when natural frequency is at zero?
That is a rigid body mode of high mass that has no oscillation.
What is 8Cr15MoV stainless steel?
This is a steel alloy.
Dad and the letters indicate the percentage of the alloy used in it.
Company name and use it in the catalog for the next operation is performed that explains it.
What is better automobile engineering or civil engineering?
I will suggest you to choose oil and gas field which has good market in upcoming years compare to other fields u can do mechanical or civil engineering both or an evergreen field.
After your engineering get specialized in Piping Engineering or Process Plant civil Engineering .
To have more confident in Piping or process plant Civil engineering field you can choose Seabird engineering institute
Is Modulus of rupture the same as Maximum stress?
Yes.
Modulus of RuptureUltimate strength determined in a flexure or torsion test. In a flexure test, modulus of rupture in bending is the maximum fiber stress at failure. In a torsion test, modulus of rupture in torsion is the maximum shear stress in the extreme fiber of a circular member at failure. Alternate terms are flexural strength and torsional strength.
What are the effects of metal impurities in iron?
Metal impurities can have many different effects on iron. Some of these effects may include, but are not limited to differences in strength, chemical inertness, and flexibility.
How do you calculate the capacity of a machine using formula?
how to calculate the embroidery machine capacity and Embroidery factory capacity and efficiency.
What you mean by cold differential set pressure of a safety valve?
cold differential test pressure -
The inlet static pressure at which a pressure relief valve is adjusted to open on the test stand. This test pressure includes corrections for service conditions of superimposed back pressure and/or temperature.
What are equivalent grades of cm 490 steel?
either S355 J2g3 or J0 depends on the sharpy value required
What is mean by economiser recirculation line?
Since sufficient feedwater is not supplied into the economizer though the heat is absorbed from flue gas at the boiler start-up and low load operation, steaming may occur in the economizer. Therefore the economizer recirculation line is provided between the furnace downcomer and the economizer inlet feedwater piping. This line provides the recirculation flow between the drum, the downcomer and the economizer so as to prevent steaming in the economizer. Economizer recirculation valve is only opened at initial stage of the boiler start-up.
What is the position of the shaft in pelton turbine?
In the center of the wheel shaft is connected to the spoon away.
What is mild steel tensile stress value in newton per square mm?
Mild steel tensile stress of 370 to 520 Newtons per square millimeter.
What are the factors on which hardness of a material depends?
Hardness of a material depends on the type of bonding between atoms.
What is mean of pump efficiency?
The ratio between the energy efficiency of pumps and pump uses the energy that does.
Pump efficiency is determined by the manufacturer.
In the calculation of pump efficiency is 70%.
How do you calculate condenser capacity?
condenser capacity(kw) = compressor cooling capacity (kw) + compressor input (kw) power
condenser capacity(kw) = Pf + Pa
What is hardness of 2062 mild steel in rockwell?
IS 2062 standard does not specify any Hardness Limit for the material. As such, even the equivalent SA36 does not specify anything on Hardness. But this being a P No.1 material in properties, the commonly accepted Hardness limit is 200HB or 93 HRB. Again there can be variation based on specific application/project requirements.
What is a gradually applied load?
It is a load applied slowly rather than quickly or suddenly. If applied quickly, the problem becomes one of dynamics, or impulse loading, but if applied slowly (gradual) it is a statics problem
What is meaning rating of pressure vessel?
A pressure vessel is built to withstand more pressure than it will ever be subjected to in practice. Such a vessel, after its construction, will be tested to see that it can safely bear far more pressure than it needs to bear while doing its normal job.
I used to play hockey with a chap who tested such vessels. We called him the "Boiler Buster".
