pls stop teaching and do something else.

give me the vr2 formula at 36:12

Barring phase change of working fluid and irreversibility of involved processes, Rankine Cycle is a practical variant of the Carnot Cycle. Thus Rankine engine relies on the heat flow into the system (with boiler as the agent for source) and on the heat flow out of the system (with condenser as the agent for sink). Rankine engine produces usefull work out of this flowing thermal energy as part of it being converted into its mechanical equivalent. Considering heat outflow from condenser, with traditional Rankine engine, the followed custom precedence is by doing artificial sensible cooling at first to effect natural latent heat release as its outcome instead of doing artificial latent heat release at first to effect natural sensible cooling as its outcome. Hence the traditional Rankine engine at large becomes bulky, suffers inefficiency (down to the order of 40%) and requires huge quantity of coolant for circulation (due to the might of latent heat). When T-S diagram is considererd, maintaining high pressure at condenser might seem paradoxical (in the context of performance enhancement) since high pressure at condenser should hamper on the performance of Rankine engine. In the contrary, compression within the condenser with sensible cooling ensures high condensation rate and increased heat outflow. As a proof of concept, Anderson condensate system in its first phase, does only partial condensation of steam (into aerosol of water droplets) that rules out substantial pressure drop within the condenser compared to traditional Rankine system whereby sensible cooling produces drastic pressure drop inside the condenser when vapour with large specific volume condenses into its liquid form. To cite with an example, the volume reduction factor due to condensation becomes 1/1600, in the case of water being taken as the working fluid. Also, regardless of the fact that Anderson system expends more power for the additionally incorporated compressor (originally intended to convert aerosol of water droplets into liquid water) that helped to produce further condensation through compression within condenser (in the second phase), the overall performance is increased by 30% and the bulk requirement of coolant is reduced, substantially. Hence compression + sensible cooling at the condenser is most desirable.

00:01 Steam turbine converts heat energy into work. 03:50 Steam turbine is used to convert steam energy into mechanical energy. 07:11 The lecture discusses the advantages and working of steam turbines. 11:07 Steam turbine efficiency is maximized by improving proximity effect. 14:36 The qualification and classification of steam engines 18:10 Steam turbine is a device used to convert thermal energy into mechanical energy. 21:52 Steam turbines work by using steam to turn blades which rotate a shaft to generate power. 25:19 The main point of the video is to discuss the classification of steam turbines.

I always get confused in relative velocity. If we add blade velocity right side ,we will get fluid velocity right side. but you add blade velocity left side.then you get fluid velocity left side.which one correct sir .kindly tell me.

Sir ap steam or boiler pir or lecture banay

12:54 For state 3 the value of gamma is not 1.4. it should be 1.34 so that T4 will come 633.49K At last of 1st numerical when we calculate efficiency, sir missed multiply 23 with denominator.

hello sir i want your contact number

Very informative video.

Great.

Thank you sir 🙏

Great lecture Sir

Hello sir, Ive studied diploma in ECE Can i Join this course

1:24 molecular weight is grams per mole, how you got kg /mole Without conversion? Can anybody answer plz

makes very easy to understand, congratulations.

Thank you sir!

Excellent sir👌

why in pump , you take change in velocity is zero.?

Background music 🎶 name?

Your education system is so good thank you again

Thank you so much Tu si great ho sir

kya bekaar chapter hai be kch smjh nhi aata

Sir you are confusing bw impulse and rxn turbine

Sir What is the value of P4' in order to calculate T5 ??

absolute waste of time eat shit man

professor sahab, it is us/cm and not us/m. And in any high pressure boiler conductivity has to be <0,2 (typical 0.1 us/cm)

looking for gold ...found the diamond

maza aa gya bhencho

In the problem the volume flow rate given is 10m3/s. In the solution you have taken it 1m3/s while calculating mass flow rate.

>mistake->value of gamma is 1.33 and u have taken 1.4

Except for the weird differential symbols used, everything is great! Love the lectures.

Thanks sir

Sir, what is turndown ratio of a burner

7:39, why inlet pressure of turbine is taken P2 , it should be P3

sir, your tutorial really helped me, thank you .... keep going

The specific ratio (γ), used for finding T4 should be that of gas (γ=1.34), NOT air (γ=1.4). Though the T4=633.56Κ is ultimately correct, when the calculations shown are performed, it gives a wrong temperature (601.4K). The reason of changed γ is because the gaseous mix in the turbine, is no longer just air but contains exhaust from the combustion stage..

budusaranai!!

Throttling loss is loss of pressure but since it is isenthalpic process can we say that it creates energy loss?

Why everyone on the internet solving these problems using Cold air assumption? How to solve its using Air standard assumption by using property tables 💔

🎉

In a furnace natural gas is combusted presence of 20% excess air. The natural gas contains 96% of methane & 4% of ethane gass. Find out the percentage of released gases in production. Help me, sir!!!

In convergent-divergent nozzle we increase the velocity of steam.in convergent nozzle M<1,means velocity of steam is less than the velocity of sound. Convergent nozzle can't increase the velocity of steam more than velocity of sound. While divergent nozzle M>1.Why do we not join convergent nozzle and divergent nozzle directly while in throat velocity remains constant?

Low Level Teaching Standards

It was nice to go through this lecture series and making notes on it. I am thankful to Prof. Ravi Kumar for this course.

In 7:42, isn't the expression for F x u signifying power ? (rather than simply work done as stated?)

5:55 Carnot Cycle

Sir hindi plz

Ravi sb., Please deliver some lectures on supercritical boilers. Regards,

How can velocity (c)= under root h1 -h2 taken here because it is taken if there is no heat transfer or work transfer but here turbine is developing work. Can anyone explain?
