Two boilers are operating steadily on 94,000 kg of coal contained in a bunker. One boiler produces 1600 kg/hr of steam at 1.2 factor of evaporation and an efficiency of 65% and another boiler produces 1464 kg/hr of steam at 1.15 factor of evaporation and efficiency of 60%. How many hours will the coal in the bunker run the boilers if the heating value is 7,600 kcal/kg

The sun generates an average of 1.958 kW/m2 when tapped as source of energy wherein a flat-plate collector with an area of 1.006 m2 is used. If the flow rate of water inside the collector is 50.1 liters per hour, compute for the possible temperature rise of working fluid in K.
3-Steam enters the condenser of a steam power plant at a flow rate of 18000 kg / h, a degree of dryness of 0.86 and a pressure of 15 kPa, leaving the condenser as a saturated liquid at the same pressure. A nearby river water is used for the cooling of the condenser. Calculate the water flow rate of the cooler if the water of the river can be heated up to 10 ° C in order to avoid thermal pollution. (C_ (p, water) = 4.18 kJ / kgK) Note: the potential energy change is negligible.
