I understand the equation, but it doesn't take into account the constant flow of water in. After doing the math with the equation you provided I get delta T to be 235 degrees celsius which seems like a ridiculous value.

Is there way to take into account a continuous input of 20 degrees Celsius water at the given flow rate?

So say I have a PV-Thermal array and assuming standard test conditions. How would I calculate the temperature of the water coming out of the system? The thermal output of the system is 67.5kWp with a maximum flow rate of 65L/h. Approximately 500m of 3/4" pipes.

relative permeability is 10,000, multiply that by uo

the question is; if there only a current in coil a, and it is AC, calculate the rms current required in coil a to maintain an alternating flux in core section a with a peak value of 1.2T calculate the rm voltages at the two coil terminals if coil resistances are neglected (attached in...

Derive a symbolic expression (i.e., a formula containing symbols R1, R2, ..., etc., andarithmetic operators instead of numerical values) for the voltage gain of the amplifier What I am stuck at is the two nodes on each side of R4 I initially disregarded the node to the right of R4, which...

The switch in the diagram below has been open for a long time prior to t = 0; then it closes at t = 0 and opens again at t = 105 µs. Find: 1. Ix(75 µs), 2. Vx(75 µs), 3. Ix(190 µs), 4. Vx(190 µs). Attached is the diagram of the circuit and its answers. so i understand how to get...
