Answer / eugene

Viscosity only applies to fluids, ie. gas and liquid.

However, the nature of viscosity for gas and liquid are
different.

In general, the liquid viscosity is dependent on the
strength of intermolecular attraction. The stronger the
intermolecular attraction, the more the viscous the liquid
is.

In fact, raising the temperature of the liquid decreases
its viscosity. This reflects the viscosity of a liquid is
indeed dependent on the intermolecular attraction.

Answer / chem

As we know what is viscosity is
Viscosty is the resistance offered in the motion of fluid.
it is the ratio of the shear stress and velocity gradient
so it depends on the following factors
shear stress
temperature
velocity

Answer / shrinivas prasad bulusuwar

viscosity is basically the resistance to flow, caused by
friction between two adjacent layers of the fluid.
The bottommost layer offers resistance to the adjacent
layer causing decrease in the velocity of the adjacent
layer.
Also, viscosity is caused due to the inter-molecular forces
of attraction.

ENGINEERING NUMERICAL METHODS - EXAMPLE 19.3 : There are 2 simultaneous equations : (A1) x + (B1) y = D1 and (A2) x + (B2) y = D2. (a) By using Excel program, find the values of x and y when A1 = 80, A2 = 150, B1 = 52, B2 = 100, D1 = 3.5 and D2 = 2.3. (b) Write the expression of Excel in the form of =MMULT(MINVERSE(W:X),Y:Z) in order to get the values of x and y. W, X, Y and Z may be A1, A2, B1, B2, D1 and D2.

A concentric, counter-current heat exchanger is used to cool lubricating oil. Water is used as the coolant. The mass flow rate of oil into the heat exchanger is 0.1 kg / s = FO. For oil, the inlet temperature TIO = 100 degree Celsius and the outlet temperature TOO = 55 degree Celsius. For water, the inlet temperature TIW = 35 degree Celsius and the outlet temperature TOW = 42 degree Celsius. What is the mass flow rate of water in kg / s, FW needed to maintain these operating conditions? Constant for heat capacity of oil is CO = 2131 J /(kg K) and for water is CW = 4178 J /(kg K). Use the equation (FO)(CO)(TIO – TOO) = (FW)(CW)(TOW – TIW).

We are having proplem with the persperation smell in ETT/ECHO room in our cardiac hospital.The 2 Ton of AC is not conditioning the environment. We have to use exhaust fan to through out of the room bad air. Could anyone suggest how to coup with this effectively using chemical engineering. Any permanent solution to neutralise the bad smell.The Air freshners are not doing enough instead making a bad odour.
