3.13 A steam power plant’s instantaneous operating conditions are summarized in Table P3.13.

For this operating condition determine

a. Boiler heat transfer rate (MBtu/h).

b. Thermal efficiency of the cycle.

c. The heating value of the coal used in this power plant is 28,262 kJ/kg. If the plant operates continuously (24 h/day) at the rate defined above, determine how many tons of coal are required per day.
