Answer / minas.v.p

Velocity is not inversely proportional to pressure. But we can use Bernaulli's theorem to find the variation of velocity with pressure.For a constant elevation problem velocity will decrease with increase in pressure,but not inversely propotional

Answer / chirag pedhadiya

city will increase with pressure bcoz pressure is a velocity increase with pressure bcoz pressure is force per unit area,now force directly propotional to accelaration,but accelaration is velocity per time ...so P directly proportional to velocity

Answer / guest

pressure is inversely proprtional to velocity.if pressure
in water line is increased velocity will be decreased

Answer / shashank

if u go with Bernoulli equation with the Increase pressure kinetic energy will decreases inorder to maintain total energy constant ( it also depends on elevation )
also when there is a pressure drop then there will be increase in velocity

Answer / nag

Water is incompressible fluid. So no effect on velocity
with pressure changes

ENVIRONMENTAL ENGINEERING - QUESTION 22.1 : In order to predict the wastewater production, the population number has to be understood. The population data is : 72000 (for year 1961 or P-1961), 85000 (for year 1971 or P-1971), 110500 (for year 1981 or P-1981). (a) Find the average population increase, or [ (P-1981 - P-1971) + (P-1971 - P-1961) ] / 2. (b) Find the average percentage population increase, or [ (P-1981 - P-1971) / P-1971 + (P-1971 - P-1961) / P-1961 ] / (2) X 100. (c) Find the incremental increase or P-1981 - 2 (P-1971) + P-1961. (d) Let Po = P-1981. After 2 decades or n = 2, the population is P-2001. By using arithmetical increase method, find P-2001 = Po + n (Answer for a). (e) By using incremental increase method, find P-2001 = (Answer of d) + n (n + 1) (Answer of c) / 2. (f) By using geometrical increase method, find P-2001 = Po [ 1 + (Answer of b) / 100 ] ^ n where ^ is power sign, or 1 ^ 2 = 1 x 1 = 1. (g) If the actual P-2001 = 184000, which method of estimation is more accurate, based on your answer in (d), (e) and (f)?

ENGINEERING DRAWING - EXAMPLE 18.3 : Autocad computer program is used to draw a pipe that is used to transport natural gases for processing. Actual length of the pipe is 10 metres. The pipe has cross sectional area of circle in shape with measured circumference of s = 3 metres. (a) If 10 units are used to represent the actual length of the pipe in computerised engineering drawing, find the diameter of the pipe, d that will be shown in the engineering drawing. (b) If one unit in the program equals to 1 centimetre, find the scale used in the computer program.
