Interpretation Introduction

Interpretation:

The depth of water at which the gate rises and permits water to flow under it is to be calculated.

Concept Introduction:

The force (F)

acting on a surface due to a fluid above it is defined as:

  F=ρgzA .......(1)

Here, ρ is the density of the fluid with height z , A is the area of the surface, and g is the acceleration due to gravity.

The force that leads any object to float when immersed partially or fully in a fluid is known as buoyancy or buoyant force. It is the result of the pressure differences that acts on the opposite sides of that object when immersed in the fluid which is static.

The tendency of any object to resist any kind of change in the velocity of that object is known as inertia.

Describe with the aid of a labelled diagram how to seperate  i) Acetone-water Azeotrope using solvent extractive distillation ii)Acetone-Methano azeotrope using salt effective extractive distillation
H.W 1. A feed of 4535 kg/h of a 2.0 wt % salt solution at 311 K enters continuously a single-effect evaporator and is being concentrated to 3.0%. The evaporation is at atmospheric pressure and the area of the evaporator is 69.7m². Saturated steam at 383.2 K is supplied for heating. Since the solution is dilute, it can be assumed to have the same boiling point as water. The heat capacity of the feed can be taken as cp = 4.10 kJ/kg K. Calculate the amounts of vapor and liquid product, and the overall heat-transfer coefficient U?
