thermodynamics   Ten kilogram of water us mixed with 12 kilogram of alcohol (SG=0.9).What is the specific gravity of the mixture, assuming that two fluidsmix completely.

Pressurized eyes Our eyes need a certain amount of internal pressure in order to work properly, with the normal range being between 10 and 20 mm of mercury. The pressure is determined by a balance between the fluid entering and leaving the eye. If the pressure is above the normal level, damage may occur to the optic nerve where it leaves the eye, leading to a loss of the visual field termed glaucoma. Measurement of the pressure within the eye can be done by several different noninvasive types of instruments, all of which measure the slight deformation of the eyeball when a force is put on it. Some methods use a physical probe that makes contact with the front of the eye, applies a known force, and measures the deformation. One non-contact method uses a calibrated “puff” of air that is blown against the eye. The stagnation pressure resulting from the air blowing against the eyeball causes a slight deformation, the magnitude of which is correlated with the pressure within the eyeball.…

Determine the output pressure of a compressor operating with the following data: a. Actual power required to drive the compressor is 20 kW. b. Overall efficiency of the compressor is 75%. c. Compressor delivers four standard m3/min. d. Compressor inlet pressure is 100 kPa abs.

What is the required diameter in meters of a cylindrical tank which has a length of 3 meters used for oil storage that will supply the engine for 5 days having a fuel consumption of 60Kg/hour at 27 degrees API? Please Answer # 9. If you can answer # 10 it will be appreciated much and rated high. Thanks!

Problem 2 Six years ago, an 80-kW diesel-electric set cost $160,000. The cost index for this class of equipment six years ago was 187 and is now 194. The plant engineering staff was considering a 120-kW unit of the same general design to power a small isolated plant that would have cost $211,707. Based on the information above the plant engineering staff is considering a 100-kW unit of the same general design to power a small isolated plant. Assume we want to add a pre- compressor, which (when isolated and estimated separately) currently costs $13,000. Determine the total cost of the 100-kW unit.
