1.A coal-burning steam power plant produces a net power of 300 MW with an overall thermal efficiency of 32 percent. The actual gravimetric air-fuel ratio in the furnace is calculated to be 12 kg air/kg fuel. The heating value of coal is 28,000 kJ/kg. Determine (a) the amount of coaal consumed during a 24-hour period and (b) the rate of air flowing through the furnace.
2.For FCC diamond cubic structures, give the lattice coordinates for the atoms found in the [100], [110], [111] direction? and Calculate the linear density of atoms in these directions for Ge.
