A solar collector for producing hot water with dimensions 2.0 m high and 1.5 m wide, and tilted 40 from the horizontal. Solar radiation is incident on the glass cover of a solar collector at a rate of 650 W/m?. The temperature of the glass cover is of 59C on and the surrounding air temperature is of 35C. The glass has transmissivity of 0.88 and emissivity of 0.90. Water enters the tubes attached to the absorber plate at a rate of I kg/min. Assuming the back surface of the absorber plate to be heavily insulated and the only heat loss occurs through the glass cover. Including radiation heat loss (surrounding temperature of 25C) and using characteristic length, 4- ,in caleulation instead of length for Reynolds, Rayleigh and Nusselt numbers. The water inlet temperature is of 28.62C, specific heat of water is of 4.180 kJ/(kg-"C) and the gravitational acceleration equal to 9.8065 m/s. Determine a) the natural convection heat loss from the collector, O. [W] b) the radiation heat loss from the collector, 1111111111 Absorber Plate Solar radiation 650 W/m T.- 35C T- 25C c) the heat transfer from the collector to water, Q [W] d) temperature rtise of water as it flows through the collector, T[C] 20m 8-3 cm Glass Cover, Insulation e) the collector efficiency, which is the ratio between amount of heat transferred or 59.0C 0 -40 transmitted to the water and the solar energy incident on the collector, n.de [%].
