Pineapple contains about 20 wt% solid and the balance water. To make pineapple jam, crush

pineapple and sugar are mixed in a mass ratio of 1:5. The mixture is heated to evaporate water until the produced jam contains 30 wt% water.

1) Draw and label a complete flow chart of the process.

2) Express degree of freedom (DOF) of the overall process (not the individual unit operation).

3) Give your comment on the DOF value.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

What is a monomer? how do they form a ploymer from the view point of chemical bonding?
