Diagram for Civil Engineering question 49

A pressure of 140 kPa is measured at Section 1-1. The inlet diameter marked at Section 1-1 is

cm, while the nozzle diameter marked at Section 2-2 is

cm. Assume the following: (i) Acceleration due to gravity = 10 m/s

. (ii) Weights of both the bent pipe segment as well as water are negligible. (iii) Friction across the bend is negligible.

The magnitude of the force (in kN, up to two decimal places) that would be required to hold the pipe section is

A consolidated undrained (CU) triaxial compression test is conducted on a normally consolidated clay at a confining pressure of 100 kPa. The deviator stress at failure is 80 kPa, and the pore-water pressure measured at failure is 50 kPa. The effective angle of internal friction (in degrees, up to one decimal place) of the soil is

An effective rainfall of 2-hour duration produced a flood hydrograph peak of 200 m³/s. The flood hydrograph has a base flow of 20 m³/s. If the spatial average rainfall in the watershed for the duration of storm is 2 cm and the average loss rate is 0.4 cm/hour, the peak of 2-hour unit hydrograph (in m³/s-cm, up to one decimal place) is ______.
