Acertain room has 2kw heat loss is to be heated by air collector of single glass cover and w=1.5m, l=3m, h=5cm 1920 w/m, 7,-25*c, ra 0.87, 4.-4.5 w/m. x,6,-0.9, & .=0.9. # the mass flow rate of air=0.27 kg/s, and inlet a temperature 45*c, will the collector is sufficient? estimate the supply air temperature and overall system efficiency. b: discuss briefly, based on the performance analysis, "a major parameters taking into account to improve the soli collectors

a displacement distance is size of displ

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

mass:

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
