How are slumps and slides different?

a. slumps are a type of sediment flow. slides are a type of slope failure.

b. slides are a type of sediment flow. slumps are a type of slope failure.

c. slumps happen very quickly. slides happen very slowly over time.

d. slides move sediment down pre- existing rock surfaces. slumps carve out curves of sediment.

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

Panel bc in fig. p2.76 is semi-circular, with the 3 meter radius and horizontal straight edge through point b. compute (a) the hydrostatic force of the water on the panel, (b) its center of pressure, and (c) the moment of this force about point b. assume atmospheric pressure on the dry side of the panel

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.
