The peak of flood hydrograph due to a 3 -hour duration storm in a catchment is $180 \mathrm{~m}^3 / \mathrm{s}$. The total rainfall depth is 6.6 cm . It can be assumed that the average infiltration loss is $0.2 \mathrm{~cm} / \mathrm{h}$. There are no other losses. The base flow is constant at a value of $30 \mathrm{~m}^3 / \mathrm{s}$.
The peak value of the 3-hour unit hydrograph for this catchment (in $\mathrm{m}^3 / \mathrm{s}$ ) is ________ (round off to the nearest integer).
In the context of construction materials, which of the following statements is/are CORRECT?
The design shear strength of a reinforced concrete rectangular beam with a width of 250 mm and an effective depth of 500 mm , is 0.3 MPa . The torsional moment capacity of the section (in kN.m) under pure torsion, as per IS 456:2000, is _________ (round off to one decimal place).
