Pressure Formula Homework: Solve 0.9/0.9 +0.1 = 0.9

In summary, pressure is calculated by dividing force by area, and can be solved for using the formula P = F/A. The SI unit for pressure is Pascals (Pa), but other common units include atmospheres (atm), pounds per square inch (psi), and millimeters of mercury (mmHg). Pressure is important in science for understanding the behavior of gases, liquids, and solids, as well as natural phenomena and technological applications. According to Boyle's Law, there is an inverse relationship between pressure and volume, meaning that as pressure increases, volume decreases and vice versa, as long as the temperature and amount of gas remain constant.

What is the course? Is the problem from your textbook?
 
  • #3


its thermodynamics and no its not from my textbook. For part a) i couldn't find a formula or anything that helps me work out the initial temperature. I'm thinking that i have to use the property tables for saturated water, and at 800kPa the saturated temperature is 170.41.would that be correct?
 

FAQ: Pressure Formula Homework: Solve 0.9/0.9 +0.1 = 0.9

What is the formula for pressure?

The formula for pressure is force divided by area: P = F/A.

How do I solve 0.9/0.9 + 0.1 = 0.9 for pressure?

To solve this pressure formula, we first simplify the left side of the equation to 1 + 0.1 = 1. Then we can rewrite the equation as P = 1, meaning the pressure is equal to 1.

What units are used for pressure?

The SI unit for pressure is Pascals (Pa), but other common units include atmospheres (atm), pounds per square inch (psi), and millimeters of mercury (mmHg).

Why is pressure important in science?

Pressure is a crucial concept in science because it helps us understand the behavior of gases, liquids, and solids. It also plays a role in various natural phenomena, such as weather and the movement of fluids, as well as in technological applications.

What is the relationship between pressure and volume?

According to Boyle's Law, there is an inverse relationship between pressure and volume. This means that as pressure increases, volume decreases, and vice versa, as long as the temperature and amount of gas remain constant.
