Consider a clay layer that is 1 m thick. The clay has a compression index of 0.35, a swell index of 0.07, a permeability of 4 x 10-7 cm/sec, a preconsolidation pressure of 172 kPa and a coefficient of consolidation of 2.7 x 10-4 cmimin The initial effective stress at the midpoint of the layer is 140 kPa, and the soil has a void ratio of 1.01. The stress is increased to 200 kPa. The soil is drained above and below. The total primary consolidation expected is 4.40 cm. How much time in days is required for 2.0 cm of primary settlement to occur?

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
