Where does your 8.1 come from? I've been using mcΔT=Q to work out how much the tank is heated up, and therefore how often I need to refill it with water. so far I've got that the tank of 545 litres heats up by about 11C every hour (if all 7kW is transferred through the pipe wall from...

Sorry I'm not sure. Initially the water would start at 20C but the pump is giving it 7kW of heat. We will allow this to take the coolant T up to around 50 degrees before passing the coolant through the cooling tank. Does that help? Sorry I can't give more info I'm still trying to wrap my head...

that equation didnt come out properly its meant to say q= (2πkl/Ln(R2-R1))*(T1-T2) is it correct to use k for the steel? or am i meant to use the value of water?

Yes the fluid is being heated before it enters the pipe (by losses from a cylinder and piston). We can assume that the 'coolant' (in this case water) is being directly given 7kW of heat at a constant rate. This coolant is then passed through the cylindrical tank to cool it down. The...

Hi Guys, this is my first post and I'd love a bit of help here, appreciated this may seem basic but it's been a few years since I did this last. I have water in a stainless steel pipe (ID = 0.0381m, OD = 0.0411m) network of roughly 10m length, at 120 bar, roughly 50°C (+ or - 5). This water...
