From what I understood while turning the refrigerant unit off the water cools too much as there's no more product to exchange heat with. This sub cooling effect makes the fluid unsuitable for the next batch and allegedly it's the reason why they are not using the unit anymore. Obviously this...

Hi there, I went to a learning visit to a small plant where it was intended to use a refrigerant cycle to cool down water used in a heat exchanger; from what I've gathered they had to stop using the refrigerant unit altogether as they're doing little batch productions per day, resulting in...

I've been able to make a spreadsheet showing how the temperature changes depending on the final H2SO4 concentration in the diluite solution, but only if both the starting 98% acid and water are at ambient temperature. I'd like to figure out how to account for the difference in temperature of the...

This is not actual work, as I said I'm not much more of a student, I only want to understand how to find a complex system curve, nobody has ever taught me this and I've only came here for some guidance to learn ! it doesn't even have to be with this specific system, anything will do. I had no...

I've only been trying to understand how to find the system curve for a complex system, it's a theoretical project and I haven't been asked to think about safety consideration as of now. Am I misunderstanding something here ?

I'm not much more of a student myself, I'm just trying to learn the job and it's my first time having to deal with some real systems rather than the basic textbook ones ! It's all very theoretical really, this won't be actually implemented in real life by me anytime soon !

Sorry for the confusion, correct: making the diluted solution is the process itself

Thank you for your answer ! You got that exactly right, it's a fast batch production. I already got all the properties and I guess I could easily derive an expression for the pump curve from its graph.

I’m trying to calculate the system curve of an already existing plant, the complexity lies in having 2 different lines, each with its respective pump 1- A substance contained in a closed tank with a liquid level of 40 ft connected to pump 1. 2- a closed tank of pure water connected to pump 2...

Thank you all for all your answers, I really do appreciate them. Datasheet data: 6 tube passes and 1 shell pass Shell diameter of 550 mm Tubes with an outer diameter of 25 mm and an average thickness of 4.5 mm 169 tubes with a pitch of 33 mm 11 baffles with a 370 mm spacing cold fluid: 203...

I’ve been trying to understand what’s the maximum mass flow that can be used in a already existing shell&tube heat exchanger. The only information i have available is the datasheet of the heat exchanger above mentioned and the fact that we want to increase the hot fluid flow from 30 ton/h to 40...
