How do you calculate pressure in open channel?

You can calculate pressure based on Piezometers but without a measurement I don't know that it is possible. I would say you can calculate the pressure force by P=Z(bar)*gama(water)*Area(of the channel).

How do you calculate pressure from wood pressing machine?

First, you must know the pressure of your hydraulic system, the diameter of the hydraulic cylinder, and the coverage of the pressure (panel surface). You may calculate total capacity of your cylinder by multiplicate system pressure by the era of cylinder. Then you have to divide this amount by the superficie of charge. Ex. Hydraulic pressure : 1200 Psi. Cylinder diameter : 100 in² Pressing era : 110 in X 220 in = 24 200 in² (1200 psi X 100 in²)/24 200 in² = 5 psi board pressure

What is the volume occupied by 27.9 of argon gas at a pressure of 1.17 and a temperature of 346?

There is no such thing as "27.9 of argon". You must specify the unit, such as moles, kilograms, etc. The same applies to the pressure and the temperature - the unit must be specified, since there are several options in each case. Once you know that, use the formula for the universal gas law to calculate the corresponding volume.
