Allow 625g per person. Roast for 15 minutes per 450g. Roast at 230Â°C/fan210Â°C/gas 8 for the first 20 minutes, then decrease the oven temperature to 180Â°C/ fan160Â°C/gas 4 for the remaining cooking time. Allow 575g per person.
the 5,000 psi is the amount of pressure the concrete can withstand  before it will crush. it has nothing to do with water proofing. to  find out if you need water proofing y â¦ ou need to know how poores the  concrete is and how quickly the ground out side will drain water.
psia, is a (pounds per square inch absolute) is a measure of the difference in pressure between a fluid being measured and the pressure of a perfect vacuum (which is, by definition, zero (0) psia on the absolute pressure scale). psig (pounds per square inch gage), as others have have mentioned is a measure of differential pressure between fluid pressure in a system, and the pressure of an environment surrounding the system. If the surrounding environment is a perfect vacuum, then psig = psia.
