Assuming that there is no possibility of shear buckling in the web, the maximum reduction permitted by IS 800-2007 in the (low-shear) design bending strength of a semi-compact steel section due to high shear is

What is the value of head loss required to initiate expansion in a rapid sand filter having depth of bed as 60 cm,porosity of medium is 0.5 and density of the medium is 2500kg/m³?

A thin plate is moving in still atmospheric air at a velocity of 4 m/s. The length of the plate is 0.8m and width is 0.6m. If density of air is 1.24 kg/m³ and kinematic viscosity is 0.15 stokes then drag force on one side of the plate is

It is proposed to drive H-piles up to a depth of 7 m at a construction site. The average surface area of the H-pile is 3 m² per meter length. The soil at the site is homogeneous sand, having an effective friction angle of 32 °. The groundwater table (GWT) is at a depth of 2 m below the ground surface. The unit weights of the soil above and below the GWT are 16 kN/m³ and 19 kN/m³ respectively. Assume the earth pressure coefficient, K= 1.0, and the angle of wall friction,
The total axial frictional resistance (in kN, up to one decimal place) mobilized on the pile against the driving is________

A lake with average surface area is 3 km² and has the water surface temperature of 28 and relative humidity of 40%. Wind velocity measured at 2m above the ground is 16 kmph . Using Meyer equation calculate the loss of volume of water in m³ . Take saturation pressure as 30.8 mm of hg and k_m = 0.

The total irrigation depth of water required by a certain crop in its entire growing period (170 days), is 33.9 cm. The culturable command area for a distributary channel is 130,000 hectare. The distributary channel shall be designed for a discharge
