Interpretation Introduction

(a)

Interpretation:

A formula for the density of the block should be derived.

Concept introduction:

It is given that a rectangular block floats at the interface between two immiscible liquids. The dimensions of the block are given as follows,

Height of the block = L

Cross sectional area of the block = A

Density of the light liquid = ρ1

Density of the heavy liquid = ρ2

Height from top surface of light liquid to the top surface of the block = h0

Height from the top of the block to the liquids interface = h1

Height from liquid interface to the bottom of block = h2

Archimedes' principle,

According to Archimedes principle the upward buoyant force that is exerted on a body immersed in a fluid, is equal to the weight of the fluid that the body displaces.

Interpretation Introduction

(b)

Interpretation:

Prove that the two approaches used to balance force on the block are correct.

A burning dump emits an estimated 1.5 kg/min of nitrogen dioxide (NO2 ). On a partlycloudy morning with a 2.5 m/s wind and temperature of 18°C, what is the concentrationof NO2 at a distance of 3.0 km directly downwind of the dump? Does this exceed theshort-term exposure limit for NO2 ? State your assumptions.

#1 A irreversible isothermal gas-phase isomerization reaction is given as: AB. This reaction is conducted in a 400L batch reactor and 100 mol of A (NAD = 100 mol) is charged into this reactor. The rate of reaction is determined as a function of the conversion of reactant A and the results are given below. The temperature was constant at 500K and the total pressure was constant at 830 kPa. The entering number of moles of species A is 100 mol. Calculate the time necessary to achieve 80% conversion. 0 0.1 0.2 0.4 -TA (mol/m³.s) 0.45 0.37 0.3 0.195 0.6 0.113 0.7 0.079 0.8 0.05
