Ok for this experiment we will be calculating with no loss and depending on the temperature of the oil it can flow around 49-47 L/min its acts as radiator as you say fluid goes in circulates around and then goes out however its a solid block not just tubing and fins if the oil flowing at...

its independent i cant ask them. the oil im using is shell heat transfer oil s2 the data for it is here: http://www.rxl-sz.com/e/products/heat_transfer_fluid/p2.html the metal im using is carbon steel and they say thermal conductivity is around 45 watts per kelvin per meter and thank you...

whats lumped capacitance meathod? and also the the oil is travelling within the metal block

sorry forgot to include that in volume of object is 361mm*361mm*50mm =0.00651605m3 density of material is 7850 kgs/m3 specific heat of material is 0.49kj/kg i dont know whats the thermal conductivity

hi, how would i calculate heating up an object with oil? the temperature of the oil is 100 degrees the object mass is 48.40kg temp to reach 100 degrees starting temp of object is 50 degrees oil is going through object so full contact

ok thank you why would i need to divide the bulk energy by a factor of 1.5? Also when calculating a object heating up time do i factor in the heat loss which will increase the time or would i put a tolerence of +/- a suitable number to make up for the heat loss ?

the equation to use to work out the power required for heating a circulating fluid: Pch = (Qm × Cp ×(t2 − t1) × 1,2) ÷ 860 -Heating power : Pch (kW) – Mass flow rate : Qm (kg/h) – Specific heat of fluid : Cp (kcal/kg × °C) – Inlet temperature : t1 (°C) – Required outlet temperature : t2 (°C)...

ok thank you the oil is flowing through fast so the oil isnt being cooked and elements wont burn please can you comment the equations that need to be used as that would be a big help thanks as i dont understand where i can find them or if they are even the correct ones

I'm trying to find the following: how much energy is used to heat the oil how long the oil can hold heat for how long it'll take theoretically for the oil to heat up to temperature and how long it'll take the oil to heat up 2 tools made of mild steel weighing around 90kg each the loop...

Ok Im using heat transfer oil so as i raise in temperature more the specific heat capacity also goes up for example from the data sheet at 100 degrees Celsius: the density of the oil is 811 kg/m 3 the specific heat capacity is 2.173 kJ/kg*K and the thermal conductivity is 0.128 W/m*K from...

the process is a project of mine, im heating objects with oil which is going through a heating unit. however rather then having a tank i have the circuit closed so its using the same oil. i was just wondering if i can calculate the energy used to heat the oil which is in constant flow in the...

I have a system which heats a fluid while in a constant flow in a loop how would i calculate the energy used to heat the fluid in the looped system to the temperature set and the time to reach it sorry if i put it in the wrong forum thank you
