Assignment-1

Precede the assignment by adding your roll number to discharge given in the table below:

Discharge at 1 week (Q) =900 + Roll number = ………………..m3/s

Table:

Week Average discharge (Q),m3/s

Week Average discharge (Q),m3/s

1 900 14 11502 920 15 10503 900 16 9154 830 17 8405 705 18 6056 600 19 5357 525 20 4908 750 21 3509 810 22 300

Other data:

Net Head (H) = 120 m

Conveyance efficiency (ηconveyance) = 70%

Turbine efficiency=85%

Generator efficiency=80%

Plot Hydrograph. Plot Flow duration curve. Plot Power duration curve. Plot the 10% of the time occurring discharge in the hydrograph. Plot the 80% of the time occurring discharge in the hydrograph. Plot the 50% of the time occurring discharge in the hydrograph. Write the discussion about choosing the design 10%, 50% and 80% occurrence discharge. By taking the firm discharge as 100% of time occurring discharge and design discharge as 50% of

time occurring discharge, calculate the firm and secondary (in GW) in the tabular form. Calculate Firm and Secondary energy (in GWh) for the period of 26 weeks in the tabular form. If the firm power is required to be increased to [450 MW + (Roll Number)] for that all period of

26 weeks, calculate the volume of storage required
