In mountainous regions, railway curves are designed to ensure the safety and comfort of passengers. The maximum degree of curvature refers to the sharpest curve that can be used safely in such regions.
According to standard engineering practices for railways, the maximum allowable curve degree in mountainous regions is typically 40°.
Thus, the correct answer is option (D).
After applying the correction for elevation and temperature, the runway length is 700 m.
The corrected runway length (in m) for an effective gradient of 1% is __________ (round off to the nearest integer).
Two soils of permeabilities \( k_1 \) and \( k_2 \) are placed in a horizontal flow apparatus, as shown in the figure. For Soil 1, \( L_1 = 50 \, {cm} \), and \( k_1 = 0.055 \, {cm/s} \); for Soil 2, \( L_2 = 30 \, {cm} \), and \( k_2 = 0.035 \, {cm/s} \). The cross-sectional area of the horizontal pipe is 100 cm², and the head difference (\( \Delta h \)) is 150 cm. The discharge (in cm³/s) through the soils is ........ (rounded off to 2 decimal places).
The most suitable test for measuring the permeability of clayey soils in the laboratory is ___________.
