energy per unit volume(ft lb/ft3= lb/ft2or Nm/m3= N/m2) The Mechanical Energy Equation in Terms of Energy per Unit Weight involving Heads The mechanical energy equation for apump or a fan(1)can also be written in terms ofenergy per unit weightby dividing with gravity -g: ...
whereE(0)=12mv02+12kx02is the mechanical energy at the initial timet= 0.Equation (10.49)implies that the change of the energy is equal to the work done by the external forceF(t) and thedamping force−cx˙. Differentiation ofEq. (10.49)gives the rate of change of the mechanical ene...
