When kaolinite clay [al2(si2o5)(oh)4] is heated to a sufficiently high temperature, chemical water is driven off.

(a) under these circumstances, what is the composition of the remaining product (in weight percent al2o3)?

(b) what is the liquidus temperature of this material?

(c) what is the solidus temperature of this material?

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux
