A canal supplies water to an area growing wheat over 100 hectares. The duration between the first and last watering is 120 days, and the total depth of water required by the crop is 35 cm. The most intense watering is required over a period of 30 days and requires a total depth of water equal to 12 cm. Assuming precipitation to be negligible and neglecting all losses, the minimum discharge (in m3 /s, rounded off to three decimal places) in the canal to satisfy the crop requirement is __________________.

As per IS456 : 2000, in which type(s) of the bars, the stress in the compression steel (f_sc) can reach the design strength (0.87 f_y) at the limit state of collapse?

Fe250 plain bars only

Fe500 deformed bars only

Both Fe250 plain bars and Fe500 deformed bars

Neither Fe250 plain bars nor Fe500 deformed bars
