3. A flat plate collector outputs 1.2 kW of power to heat water in a storage cylinder. If the water flows through the collector at a rate of 0.04 kg/s, what increase in temperature can be achieved? (Specific Heat of Water Cp = 4179 Jkg-1K-1)
4. If we decrease the thermal resistance of a flat plate collector, this leads to;
