Its really great.its helping me in preparing for my seminar.

A large truck is to transport 30,000 Kg of orange pre-cooled to 4oC under average temperature of 27oC. The structure of the walls of the truck is such that the rate of heat transportation is UA=80W per oC temperature difference between the ambient and the oranges. From past experience, ambient air is estimated to enter the cargo space of the truck through the cracks at a rate of 4L/s. Also, the average heat of respiration of the oranges at 4oC is 0.017W/kg for this particular load. Disregarding any condensation and taking the density of air to be 1.15kg/m3, determine the refrigeration load of this truck and the amount of ice needed to meet the entire refrigeration need of the truck for a 15hour trip.

Can you help me on figuring out how to start this question?

An invaluable source. Really great. I have enjoyed a good few of them, and keep referring other people to go to the page or share the videos. They are just awesome.

Thanks for sharing them.

how much power is required for a reciprocating pump to flow the jet with a speed of 80m/s

Thanks great videos

This is an excellent forum.

I think that's a valuable resource for explaining why aircrafts fly.

BTW Hello everybody! Long time no see you! I work now in the bay area in a well known university: Fear the tree! :)

Hope all is well with you.

Exceptional thanks bro :surprised

I had a very poor fluid mechanics experience at my university. I look forward to viewing these videos!

Wow! These are great! Thanks Clausius2

Also - has anyone here read L D Landau's book on fluid mechanics? Im tempted to purchase it, but I dont know much about it....

Hi, I am sorry to deviate a little from the topic but I need some help. I am a mechanical engineering student in Dubai and I am currently doing a project on RO systems. I have to look into how the feed pressure/operating pressure affects the cost of RO systems and also the operating costs of an RO system. Can anyone help me find some resources? Because I am not finding anything that specifically tells me how the cost is affected by the pressure or the operating cost. Please I would really appreciate if someone could help me. Thank you
