Answer / kaushik

for equal ditribution of pressure

Answer / giri

because spheres are having constant surface per unit area.
so distribution of preesures will b equal at all points.

Answer / murthy

there are mainly two considerations before designing
storage vessel of flammable liquids.
(1)the temperature removal should be very fast,there is lot
of heat loss in spherical design,than tubular one,so heat
removal is more.
equilibrilium between vapor and liquid will shifted towards
liquid side when stored in spherical cylinders.
(2) requirement of inert gas for padding is greatly reduced
in case of spherical cylinders as vapor pressure of liquid
is reduced due to reason 1

CHEMICAL FLUID MECHANIC - EXAMPLE 3.3 : 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.

Question 71 - (a) The byte is the basic building block of computer data used in chemical engineering process simulation where 16 bits make a word, 4 bits make a nibble, 32 bits make a quad word and 8 bits make a byte. Then how many nibbles are there in a megabytes? (b) In computer data items, let : 1 bit - counts from 0 to 1, 8 bits - counts from 0 to 255, 16 bits - counts from 0 to A. What is the value of A? (c) In a binary system of 4 bits, if 1100 = 12, 1101 = 13, 1110 = 14, 1111 = 15, B = 16, then guess the value of B. (d) By using any form of tools, find the exact value of 2 power 64 or 2^64.
