In the following level tank the entering stream undergoes a wavy change of 4 sin 1.3t m^3/min. Develop the deviation dynamic model. Find the deviation in the
liquid height as a function of time. Find the height of the liquid in the tank after 2 min the deviation occurs. Density is constant. Cross-sectional area of the tank, A =2.1 m^2.

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?

Plan an experiment to measure the surface tension of a liquid similar to water. if necessary, review the ncfmf video surface tension for ideas. which method would be most suitable for use in an undergraduate laboratory? what experimental precision could be expected?
