Asimple rankine cycle with water as the working fluid operates between the pressure limits of 4 mpa in the boiler and 20 kpa in the condenser and a turbine inlet temperature of 700oc. the boiler is sized to provide a steam flow of 50 kg/s. determine the power produced by the turbine and consumed by the pump.

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.

If an atom contains 11 protons in its nucleus, predict the element with the atomic number and electronic configuration. will the number of electrons remain the same during the chemical reaction in such an atom? explain.

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
