By J R Backhurst, J H Harker, J.F. Richardson

This quantity within the Coulson and Richardson sequence in chemical engineering includes complete labored recommendations to the issues posed in quantity 1. while the most quantity includes illustrative labored examples through the textual content, this publication includes solutions to the tougher questions posed on the finish of every bankruptcy of the most text.

those questions are of either a customary and non-standard nature, and so will turn out to be of curiosity to either educational employees instructing classes during this quarter and to the prepared pupil. Chemical engineers in who're trying to find a typical method to a real-life challenge also will locate the ebook of substantial curiosity.

* a useful resource of data for the scholar learning the cloth contained in Chemical Engineering quantity 1
* A useful approach to studying - solutions are defined in complete

Brewing (RSC Paperbacks)

It truly is believed that beer has been produced, in a few shape, for millions of years - the traditional Egyptians being one civilization with a data of the fermentation procedure. Beer creation has visible many adjustments over the centuries, and Brewing combines either an old examine the method with a few up to date advancements.

Transport Processes in Pharmaceutical Systems (Drugs and the Pharmaceutical Sciences)

This state-of-the-art reference basically explains pharmaceutical shipping phenomena, demonstrating purposes starting from drug or nutrient uptake into vesicle or mobile suspensions, drug dissolution and absorption throughout organic membranes, complete physique kinetics, and drug unencumber from polymer reservoirs and matrices to warmth and mass shipping in freeze-drying and hygroscopicity.

Green Energetic Materials

Because the finish of the twentieth century it's been more and more realised that the use, or construction, of many lively fabrics results in the discharge of gear that are damaging to either people and the surroundings. to handle this, the foundations of eco-friendly chemistry should be utilized to the layout of recent items and their production approaches, to create eco-friendly lively fabrics which are almost freed from environmental risks and toxicity concerns in the course of production, garage, use and disposal.

0005 respectively. From Fig. 6 kN/m2 In addition, there will be a small pressure drop at the junction of the two pipes although this has been neglected in this solution. Thus the existing pump is satisfactory for this duty. 11 Explain the phenomenon of hydraulic jump which occurs during the flow of a liquid in an open channel. 5 m/s and a depth of 75 mm. Calculate, from first principles, the corresponding velocity and depth after the jump. 9. 12 What is a non-Newtonian fluid? Describe the principal types of behaviour exhibited by these fluids.

After a length l, the liquid is discharged into a tank. 5 Assume a fully developed flow with R/ u2 D 8 Re 1 . 15 m diameter to storage tanks situated 100 m away. The pressure drop along the pipe is 70 kN/m2 . The pipeline has to be repaired and it is necessary to pump the liquid by an alternative route consisting of 70 m of 200 mm pipe followed by 50 m of 100 mm pipe. If the existing pump is capable of developing a pressure of 300 kN/m2 , will it be suitable for use during the period required for the repairs?

12 What is a non-Newtonian fluid? Describe the principal types of behaviour exhibited by these fluids. 5 where a is the viscosity, and du/dr is the velocity gradient normal to the direction of motion. Show that the volumetric rate of streamline flow through a horizontal tube of radius a is: P 2 a5 5 2kl where P is the pressure drop over a length l of the tube. 123. 5 The fluid is therefore shear-thinning. 025 N s/m2 ). 002. From Fig. 0046. 32 m/s. 14 The relation between cost per unit length C of a pipeline installation and its diameter d is given by: C D a C bd where a and b are independent of pipe size.
