19	The peak load on a 50 MW power station is 39 MW. It supplies power through 07 2 four transformers whose connected loads are 17, 12, 9 and 10 MW. The maximum demands on these transformers are 15, 10, 8, and 9 MW respectively. if the annual load factor is 50% and plant is operating for 65% of the period in a year, find out the following: (i) Average load on the station (ii) Energy supplied per year (iii) Demand factor (iv) Diversity factor (v) Power Station use load.-WINTER 2015.
20	Calculate the cost of generation per kWhr for a power station having following data: Installed capacity of plant =200MW; Capital cost=Rs400; crores Rate of interest and depreciation =12% Annual cost of fuel , salaries and taxation=Rs 5 crores; Load factor=50%. Also estimate the saving in cost per KWhr if annual factor is raised to 60%.- SUMMER 2014
21	Derive an expression for chimney height in order to obtain a draught of ‘h’ mm of water column if the boiler used ‘m’ kg of air/kg of fuel. Assume, surrounding air temperature as ‘Ta’ and flue gas temperature as ‘Tg’ in degree absolute. Also derive an expression for the condition of maximum discharge of flue gases through a chimney.- WINTER 2016
