Liquid water at 300 kpa and 20°c is heated in a chamber by mixing it with superheated steam at 300 kpa and 300°c. cold water enters the chamber at a rate of 2.4 kg/s. if the mixture leaves the mixing chamber at 60°c, determine the mass flow rate of the superheated steam required. (round the final answer to three decimal places.)

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
