Calculating the Reynolds number.
find out Reynolds number if water at 15°C is flowing through a 3cm diameter pipe with a velocity of 50 cm-1. Is flow turbulent or laminar?
(At 15°C water has density of 999.1 kgm-3, and viscosity 1.14 x 10-3 Nsm-2)
1. What is the constant of proportionality? 2. Confirm that the above sum-product algorithm does compute P(t n =t| y)
A woman drives a car from one city to another with different constant speeds along the trip. She drives at a speed of 65.0 km/h for 15.0 min, 70.0 km/h for 25.0 min, makes a stop for 40.0 min, then continues at 45.0 km/h ...
At any time, t, a population, P(t), is growing at a rate proportional to the population at that moment. (a) Using derivatives, write an equation representing the growth of the population. Let k be the constant of proport ...
A remote controlled car has a momentum given by p = [(0.43 kg*m/s²) t²- (0.2 kg*m/s²) t ] î + (0.87 kg*m/s²) t j. What are the x- and y-components of the net force on the car.
Consider the function f(x) = . (a) Find and sketch f(x) and the tangent line approximation to f(x) near x = 4. (b) Compare the true value of f(4.1) with the value obtained by using the tangent line approximation. (c) Com ...
Assume that a sequence of symbols from the ensemble X introduced at the beginning of this chapter is compressed using the code C 3 . Imagine picking one bit at random from the binary encoded sequence c = c(x 1 )c(x 2 )c( ...
Explain why the first tropical storm of the Atlantic hurricane season is more likely to form in the Gulf of Mexico than off the west coast of Africa.
Dependence on crossover mechanism. In the simple model of sex, each bit is taken at random from one of the two parents, that is, we allow crossovers to occur with probability 50% between any two adjacent nucleotides. How ...
1. For a crystal of finite size it Is found that there are 100 allowed electron energy levels at the energy E 1 in the conduction band and that the Fermi energy lies at E 1 , i.e. E F -E 1 . How many electrons are there ...
The ''soil venting'' shown in the figure below is used to treat soil contaminated with volatile, toxic liquids. In the present situation, the porous soil particles are saturated with liquid TCE, a common industrial solve ...
