Arankine cycle with one closed feedwater heater with its drain cascaded backward has a water mass flow rate through the steam generator of 140 kg/s. superheated steam enters the turbine system at 19.3 mpa and 5408c, and saturated liquid water exits the condenser at 28 kpa absolute. the closed feedwater heater receives extracted steam from the turbine at 2.4 mpa absolute, and the temperature of the feedwater exiting the closed feedwater heater is 2108c. determine the net power produced by the cycle and the thermal efficiency of the cycle if (a) the turbine and pump are isentropic, and (b) the turbine isentropic efficiency is 0.82 and the isentropic efficiencies of the pump is 0.65.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendel’s discoveries in genetics. over a century later, darwin’s idea of evolution was modified in order to incorporate mendel’s rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendel’s rules of genetics and darwin’s idea of biological evolution? a.)mendel’s genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendel’s theory of genetics.c.)mendel’s genetics replaced darwin’s entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
