6- The figure shows a solar collector panel with a surface area of 2.97 m. The panel receives energy from the sun at a rate of 1.5 kW. Thirty- six percent of the incoming energy is lost to the surroundings. The remainder is used to heat liquid water from 40°C to 60°C. The water passes through the solar collector with a negligible pressure drop. Neglecting kinetic and potential energy effects, determine at steady state the mass flow rate of water, in kg/min. rA=2.97 m Water in 1.5 EW Solar collector pened Water out at 40 C 36% loss at 60C Useful I data: Gas Molar mass- M-, kg/k mol Y = C/C Air 28.97 32 58 1.4 охудen 1.4 Butane (CH10) Nitrogen (N2) Methane (CH) 1.1 1.4 1.32 28 16 Universal gas constant 8.314 kJ / kmol.
