Believing that 70% of her body is composed of water, and 20% is composed of denser materials (bones, teeth, etc.) with a specific gravity of 1.25, what is the specific gravity of the remaining 10% of her body/internal composition? (specific gravity is just the ratio of density of a material to water. thus, a specific gravity of 1.25 corresponds to a density of = 1.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
