A Carnot heat pump is to be used for heating house in winter. The house temperature is set at 25oC. One day the outdoor temperature is 2oC. The house is estimated to lose heat at a rate 55000kJ/h (which equal to Qout of the heat pump).
a 5 cm layer of insulation with thermal conductivity of 0.06 wm.c is placed between two plates of 100 and 200 degrees
Niobium has the BCC structure with a density of 8.57 g/cm^3 , an atomic weight of 92.91 g/mol. One atom is associated with each lattice point. Calculate the lattice parameter; and the atomic radius of Niobium.
