Which equation is an expression of the rate law?
Rate = k[A]m[B]n
What is a factor held constant?
In science, as in real life sometimes several 'factors' effect the outcome of an experiment. In order to make the problem easier to study one or more of these is 'held constant' or not allowed to change in order to see the effect of the other variables. EX. Gas volume can be effected by both pressure and temperature. In order to understand the effect of pressure, Boyle kept the temperature constant. He then changed the pressure to see what happened to the volume of a gas. This gave him what is now called Boyle's Law: The volume of a gas varies inversely as the pressure when the temperature is held constant.
Can you give an example of a sentence using the word equal?
The two amounts were equal. In the eyes of the law both claims were determined to be equal. She mixed equal amounts of rice and water.
How do engineers use algebra?
Algebra is one of the most fundamental tools for engineers (and physicists) because it allows them to determine the value of something (length, material constant, temperature, mass, and so on....) given values that they do know (possibly other length, material properties, mass......).Although the types of problems that different types of engineers (mechanical, chemical, civil, environmental) deal with varies a lot, all engineers use algebra to solve problems. Mechanical engineers, for example, will usually use calculus to determine the dimensions a certain part may need to be, but in situations where things are constant, it is much faster to simply use algebra. For example, in a situation where there is constant acceleration (due to something simple like gravity) and an object with constant mass, newton's 2nd law (Force = mass * acceleration) may be quickly used to determine the force associated. In most situations, however, the acceleration will not be constant, so calculus will need to be used.Another example of where algebra is frequently used is in simple electrical circuits, where the resistance is "ohmic", or linearly proportional to voltage. Using "Ohm's Law," or V=IR, an engineer may simply divide the voltage of a circuit by the current that they desire (for whatever reason) to determine the type of resistor they should put in the circuit.UNICORNS AND GIRAFFES ARE AWESOME!!!!!!!!!!!!!!!!!!!!!!!

How do you convert water flow in litres per min to pressure in bar?
The relationship between pressure and flow is given by Bernoulli's law. In an idealized system, the speed increases with the square of the increase in pressure. The flow rate would be given by multiplying the area of the outflow by the speed.
