A consolidated-undrained triaxial test is conducted on a saturated sand specimen, and the following data is obtained: the chamber pressure is 120 kPa, the deviator stress at failure is 80 kPa, and the pore water pressure at failure is 50 kPa. What is the total axial stress at failure

Fluids at rest possess no flow energy. a)- true b)- false

Water at the rate of 1 kg/s is forced through a tube with a 2.5 cm inner diameter. the inlet water temperature is 15°c, and the outlet water temperature is 50°c. the tube wall temperature is 14°c higher than the local water temperature all along the length of the tube. what is the length of the tube?
