A photovoltaic panel of dimension 2mÃ—4m is installed on the

roof of a home. The panel is irradiated with a solar flux of GS =700W /m2, oriented normal to

the top panel surface. The absorptivity of the panel to the solar

Irradiation is s =0.83, and the efficiency of conversion of the absorbed flux to electrical power

is P /sGsA =0.553âˆ’0.001Tp, where Tp is the panel temperature expressed in Kelvins and A is

the solar panel area. Determine the electric power generated for

a. A still summer day, in which Tsur =T[infinity]=35C, h=100W /m2 â‹…K, and

b. A breezy winter day, for which Tsur =T[infinity]=âˆ’15oC, h=30W /m2 â‹…K. The panel Emissivity is 0.90.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
