Laboratory specific gravity and absorption tests are run on two coarse aggregate sizes, which have to blended.
The results are as follows:
Aggregate A: Bulk specific gravity 2.491; absorption 0.8%
Aggregate B: Bulk specific gravity 2.773. absorption 4.6%
a. What is the specific gravity of a mixture of 50% aggregate A and 50% aggregate B by weight?
b. What is the absorption of the mixture?
c. What should be the proportion of aggregate A in the blend, so that the mixture will have a bulk specific gravity of 2.650?
d. What should be the proportion of aggregate A in the blend, so that the mixture will have an absorption capacity of 4%?

Water vapor initially at 10 bar and 400 °c is contained within a piston-cylinder assembly. the water lost heat to the surrounding according to isochoric (iso-volumetric) process until its temperature is 150 °c. the water is then condensed isothermally to saturated liquid. for the water as a system, calculate the work in kj/kg
