Answer / engr. muhammad omer farooqi

density=mass/volume (density is equal to mass in a unit volume). Water being a liquid has its molecules in more compact form as compared to any gas; implying more mass in same amount of volume. Remember, in general, order of densities is as follows: solids>liquids>gases

Answer / kundan singh

water.bze in a given region water contain more molequle then gas.

Answer / m.s.amusadhurai

In water the density is high because of more molecules in
defined area due to hydrogen bonding between the water
molecules whereas in the gas the hydrogen bonding is very
less so the distance between the molecules is high hence
density is less

Answer / poonam

of course water because water is in liquid state and
liquid's are more denser than gas.

Answer / swapnil kale

offcourse water, since intermolecular force of attraction
in water is high as compared to gas, so in water more no.of
molecules can b hold in given volume as compared to gas,

In DM plant, If pH in anion outlet is 7.2 and Mixed bed pH is 6.2, wat could be the reason.

Question 66 – The drag coefficient Cd = 0.05 and lift coefficient Cl = 0.4 for a levelled flow aircraft are measured. The velocity of the aircraft is v = 150 ft / s with its weight W = 2677.5 pound-force. (a) Find the value of the lift of the aircraft, L, when it is also its weight. (b) The drag of the aircraft, D = Cd M, L = Cl M. Find the value of D. (c) The power required is P = Dv. If 1 pound-force x (ft / s) = 1.356 W, find the value of P in the unit of Watt or W.

REACTION ENGINEERING - EXAMPLE 13.1 : In a furnace, 2 chemical reactions are happening - 1 mole of solid carbon reacts with 1 mole of oxygen gas to generate 1 mole of carbon dioxide gas; 1 mole of solid carbon reacts with 0.5 mole of oxygen gas to generate 1 mole of carbon monoxide gas. In a given process, 100 kmol of carbon is burned in a furnace. (a) Calculate the theoretical oxygen gas needed by assuming that all the carbon is burned completely to carbon dioxide gas. (b) Calculate the theoretical air needed by assuming that all the carbon is burned completely to carbon dioxide gas and there is only 21 % of oxygen gas. (c) Determine the amount of air required (in kmol) if 50 % excess oxygen gas must be satisfied for (a) and (b). (d) It has latter been found that 20 % of the carbon undergoes incomplete combustion resulting to carbon monoxide gas production. The rest of the carbon undergoes complete combustion. Calculate the total oxygen gas required stoichiometrically based on the actual process.

QUANTUM CHEMISTRY AND CHEMICAL ENGINEERING - EXAMPLE 31.1 : As an approximation, let v = Zc / 137 where v is the radial velocity for 1 s electron of an element, c is the speed of light, Z is the atomic number. For gold with Z = 79, find the radial velocity of its 1 s electron, in term of c and percentage of the speed of light. (b) As an approximation, let A x A = 1 - Z x Z / 18769 where A is the ratio of the relativistic and non-relativistic Bohr radius. Find the value of A.
