water is pumped from a lake to a storage tank 20 m above at a rate of 70 ls while consuming 20.4 kw of electric power.
Explain the inter-relationships between the different processes and functions you have identified within your organisation and identify and explain engineering business functions.
Obtain the differential equation and the boundary and initial conditions that could be solved to determine the tem- perature as a function of position and time in the bar.
Sketch a diagram of the system. Use free-body diagrams to write each of the two mechanical equations. Set up the equations in matrix form.
