Example Problem - Rankine Cycle (2) - Rankine Cycle with Reheating
Просмотров 15 тыс.4 года назад
Consider a reheated Rankine cycle using steam as the working fluid. Steam leaves the boiler and enters the turbine at 4 MPa, 400°C and is expanded in the low-pressure turbine to 10 kPa. An engineer is considering adding a 400 kPa reheat stage to this facility, which would bring the steam back up 400°C before expanding again. Determine/complete the following: (a) η_th of the facility without reh...
Example Problem - Heat Capacity (2) - "The Coffee Problem"
Просмотров 1,5 тыс.4 года назад
John, like most people in the STEM fields, has an unhealthy addiction to caffeine but he can totally quit whenever he wants. He just doesn’t want to. Anyway, let’s say he gets up in the morning and brews a fresh pot of coffee, and pours 16 oz (473.2 mL) into a well-insulated thermos to bring along to his 8:00 AM class. When it is poured, the coffee is about 94°C, which is way too hot for John t...

Steam is the working fluid for an ideal Rankine Cycle. Saturated vapor enters the turbine at 8.0 MPa and saturated liquid exits the condenser at 0.0075 MPa. The net power output of the cycle is 100 MW. Determine: (a) η_th (b) BWR (c) m ̇_steam in kg/hr (d) Q ̇_in (e) Q ̇_out (f) If the condenser is cooled by a stream of cooling water entering the condenser at 15°C, determine the minimum stream ...

A piston-cylinder device contains 0.005 m^3 of liquid water and 0.9 m^3 of water vapor in equilibrium at 600 kPa. Heat is transferred at constant pressure until the temperature reaches 200°C. Determine the following: The initial temperature of the water (°C) The total mass of the water (kg) The final volume (m^3) The amount of work done in the process (kJ) The amount of heat transferred during ...
Example Problem - Bernoulli's Principle
Просмотров 4,2 тыс.4 года назад
A necked-down section in a pipe flow, called a venturi, develops a low throat pressure that can aspirate fluid upward from a reservoir, as in the figure below. Consider a venturi used to pull gasoline (SG=0.72) up from a fuel tank. The fuel in the tank is exposed to atmospheric pressure, and the air entering the venturi is traveling at 3 m/s through a 5 cm diameter tube. The fuel needs to be pu...

Example Problem - Brayton Cycle as a Turbojet (Cold-Air Standard)
So the question must be asked, did four cubes actually do the job?
You bet!
Very underrated
Hey can you please check the link to the pdf cuz it's not working
What changes in this system is it's non-ideal?
What book are you using?
This is awesome! Thank you! Do you have a video for the matlab code?
My professor needs us to model a rocket, I didn’t know what to do so I ran here 😂
Hello. What book are you using?
your series is actually pretty helpful
what app do you use to sketch it
Hello, why do I see some people with h5, they immediately equate it with h3? Does it matter if I do interpolation using their temperatures or using h3 as h5?
Damn this video was awesome
Thank you so much
why the average velocity is not squared
Thank you so much. This is very useful for my exam.
You are a rare person among the gifted in that you are a generious educator. People like you are part of the beauty of this world. Thank you.
I think there is mistake in the final answer of mass flow rate, you did not add 200 m/s to dinominator. thanks for helping.
Thank you so much, I listen in class and my lecturer is a great man but for some reason, I am always confused, this is helping.
Thanks a lot for this. You don't know how much it helps
You literally saved the semester
I gotchu fam
Muchas gracias, es una excelente información, usted habla de tal manera que se le entiende perfectamente, thank you!
John, this better not be on our final today
thoses videos are just extrordinary. you helped me understand the content in a way nobody could. thank you a lot <3
explained it all while my teacher has absolutely no clue about this I guess!
hey, can someone explain how the hydrostatic force equal to the weight of missing water ?
1:38 V^2/R
Awesome study content for my Thermo exam!
really doubt I'll get an answer here but why do we use internal energy for process 1 to 2 but enthalpy for process 2 to 3 even though there's work done in both processes.
Both have work, but 2 to 3 also has heat transfer
Extraordinary teaching skills! Grateful for the entire thermo playlist.
can we have the pdf of the tab el you are using
It was something beyond excellent.
Wonderful explanations, exactly what I was looking for. The additional information/real life applications of this was very insightful as well. Thank you!
Brayton cycle with regeneration 's main videos got removed i believe, it would be nice if you look into it sir.
These examples are top-notch. i have 0 clue why this channel does not have more views
Is there a playlist for the entirety of vapor compression refrigeration cycle? This is a very good video and I learned a lot. I would definitely want to learn more. Thank you
23:50 i wish i could do math in xm by snapping
I like the conversations with the calculator
Thank you for a phenomenal explanation with such precision and clear assumptions! This is exactly the type of clarity I seek to solve problems and is the same approach I try to use when I teach students. Thanks!
this guy very underrated
awesome
really good. thanks.
SSS Tier Video much love <3
this is super helpful but I wish you had a link to the powerpoint or notes pdf so we can easily follow along on iPad/personal device.
Very well explained, thank you.

Why, why volume doubled. Matter doesn't change also elevation of water level reduce 1/2. How we can say volume doubled
The volume doubled as a result of the way the problem was set up. Initially half the volume was in vacuum, separated from the rest of the apparatus by a barrier. We are considering what would happen if that barrier instantly disappeared - the same matter now occupies twice the volume. The water level doesn’t reduce by half, as the vessel was not initially filled with water and air, it was just water - the phase changes to accommodate the volume (as a result of pressure)
But water does not compressible above their limit as we consider as Newtonian fluid. Also after expansion, water covered by doubled volume. That's not sense right? I know question says that but let exception from question and consider normal condition. Is it possible in real life?@@Thermofluids
awesome videos! please continue making more!
I dont know you your subscribers are so less,must appriciate the confidence you pass on us to solve question....simply made concepts so easy and clear.Thanks a lot!!!
Thank you so much sir, i really appreciate this video.
I keep getting 206
