A solar collector consists of a flat plate that absorbs the heat
of sunlight. A water pipe attached to the back of the plate carries
away the absorbed heat. Assume that the solar collector has an area
of 4.9 m2 facing the Sun and that the power
per unit area delivered by sunlight is 1000 W/m2.
What is the rate at which water must circulate through the pipe if
the temperature of the water is to increase by 31 C as it passes
through the detector?
total power received by solar collector is
P = 1000 x 4.9 = 4900 W
the specific heat capacity of water is 4186 J/kg/C
The rate at which water must circulate through the pipe if the temperature of the water is to increase by 31 C is

A flat plate collector mounted on plane surface operates with efficiency of 40% it installed at a location 45◦ N, the time is 10:00 am, April 1, 2019. When the collector faces the sun directly it delivers 870 W to the water, how much power will deliver if the surface is set at an elevation of 25◦ and facing east? You can assume that the conversion efficiency from solar power to power absorbed by the fluid remains constant, what changes...
A flat-plate solar collector is used to heat atmospheric air flowing through a rectangular channel. The bottom surface of the channel is well insulated, while the top surface is subjected to a uniform heat flux 96,which is due to the net effect of solar radiation absorption and heat exchange between the absorber and cover plates. W Transparent cover plate Absorber plate Rectangular channel Air Tmi, m Beginning with an appropriate differential control volume, obtain an equation that could be used...
An unglazed flat plate solar water heater is orientated perpendicular to the sun such that the incident radiation reaching the plate is 1100 W/m2. The plate has a semi selective coating such that the plate absorptivity and emissivity is equal to unity for all wavelengths up to 2µm, and 0.13 for all λ > 2µm. Coolant flowing in the collector tubes removes heat at such a rate as to maintain the plate temperature at 80°C. Considering the sun to be...
Determine the overall heat transfer coefficient (UL) for a Flat Plate Solar Collector inclined at 45 degrees to the horizontal and facing south. The average ambient temperature for the day is 20 degrees C and the observed glass and absorber plate temperatures are 45 degrees C and 69 degrees C respectively. The system is provided with 6 cm thick insulation (glass wool, k = 0.04 W/m degrees C) at the bottom. The air space between the absorber plate and glass...
In a solar water heater, energy from the Sun is gathered by water that circulates through tubes in a rooftop collector. The solar radiation enters the collector through a transparent cover and warms the water in the tubes; this water is pumped into a holding tank. Assume that the efficiency of the overall system is 29.0% (that is, 71% of the incident solar energy is lost from the system). What collector area is necessary to raise the temperature of 430...
