Figure shows a single-solar-collector panel with a total surface area of 2.97 m^2. The panel receives its energy from the sun at a certain rate. However, thirty-six percent of the incoming energy is lost to the surroundings. The remaining energy is used to heat liquid water from 40 C to 60 C. The water passes through the solar collector with a negligible pressure drop at a rate of 0.0310 ??/?. By neglecting the kinetic and potential energy effects/differences through the pipe lines, a. Determine the outer surface temperature of the Sun. b. How many “Liters” of water at 60oC can the collector provide in a 30-min time period?

Figure shows a single-solar-collector panel with a total surface area of 2.97 m^2. The panel receives its energy from the sun at a certain rate. However, thirty-six percent of the incoming energy is lost to the surroundings. The remaining energy is used to heat liquid water from 40 C to 60 C. The water passes through the solar collector with a negligible pressure drop at a rate of 0.0310 ??/?. By neglecting the kinetic and potential energy effects/differences through the pipe lines,
a. Determine the outer surface temperature of the Sun.
b. How many “Liters” of water at 60oC can the collector
provide in a 30-min time period?
Transcribed Image Text:Figure shows a single-solar-collector panel with a total surface
area of 2.97 m. The panel receives its energy from the sun at a
certain rate. However, thirty-six percent of the incoming energy
is lost to the surroundings. The remaining energy is used to heat
liquid water from 40°C to 60°C. The water passes through the
solar collector with a negligible pressure drop at a rate of
0.0310 kg/s. By neglecting the kinetic and potential energy
effects/differences through the pipe lines,
a. Determine the outer surface temperature of the Sun.
b. How many "Liters" of water at 60°C can the collector
provide in a 30-min time period?
