Diesel cycle || Air standard cycle ||Thermodynamics Part -09

    Air standard  cycle :                                                        

Diesel cycle : Diesel engine work on the diesel cycle and it consist of two isentropic process and one isobaric process , one  isochoric process .

    Isentropic process : Compression process : Air is compress at isentropic process 

Isobaric process : Heat addition , increasing pressure of gas at isobaric process 

Isentropic process : Expansion process , Where fuel and compressed air contact so fuel will burn and produce heat and pressure so power will generate .

Isochoric process : Where the exhausted gas is remove from combustion chamber at isochoric process

Below diagram between pressure and volume & entropy and temperature 


 Efficiency of diesel cycle : Output / Input

Where the r is compression ratio and rc is cutt off ratio

Compression ration for diesel cycle 12-16 
Compression ratio for petrol engine  5-6 
Compression ratio for dual cycle  6-8

Continuity equation & types of flow |FLUID MECHANICS ||PART -4

Image
Basic terminology of fluid mechanics  Steady flow : In this flow velocity of fluid particle don't change with time at fixed point of fluid is called steady flow. Unsteady flow: In this flow velocity of particle change with time at fixed point of fluid is called unsteady fluid . Uniform flow : In this flow the magnitude of flow don't change (same ) at point of fluid . Non-uniform flow: In this flow the magnitude of flow  change (different) at point of fluid . Laminar flow :   In this flow fluid particle move in smooth and regular in motion is called laminar fluid is called laminar fluid and it is also  called steam line flow . Turbulent flow :   In this flow fluid particle move in randomly  and irregular  in motion is called laminar fluid is called laminar fluid. Continuity equation : According to this law the inlet fluid is equal to outlet fluid this law based on the conservation of mass . Q = p.A.V   Where the Q is discharge of fluid and p is...

CASE STUDY at ZOMATO

Image
Case study at zomato :   Zomato initially named as Foodiebay was started in 2008 by Mr. Deepinder Goyal. It is a restaurant searching platform providing in-depth details with autonomous reviews and ratings. Foodiebay, the initial name was changed to Zomato in November 2010 to increase their reach among people. To differentiate themselves from their competitors, Zomato concentrated on adding approx. 18,000 new places to eat from. Along with they also decorated many special features, such as pointed to particular dishes or opening times”. To be the largest resource in food supply market, Zomato bought urbanspoon, a leading restaurant service providing portal for $52 million to enter US, Canada and Australia to leverage local insights and experience and to expand their business in overseas seeing the future goal and objective.   To expand to more 50 countries Milestones: Number of listed restaurants: in 2008 it was 4000 restaurants which increase to 94000 in 2013 and current...

Interview questions for mechanical engineering

Q.  What is elasticity?  Ans. It is the propertyof material where apply deforming force on the body  so body is deformed,  it will regain its original shape after removing deforming force.  Q. What is plasticity?  Ans. It is the property of material where apply deforming force on the body so it will permanently deformed after removing deforming force.  Q. What's brittleness?  Ans. It is the property which is distortion  of material when applying impact load  or it will break in small parts.  Compressive strengh is high and tensile strength is low.  Q. What is creep?  Ans. It is the property of material which have slow permanent deformation  within temperature along long time.  It's occure in belt  Q. What's toughness?  Ans.is the property of material,Which is resist the high impact load for short time. That is callled toughness.  Q. What's Malleability  ??  Ans.  It the property of m...
