Is the amount of pressure in a gas measured in pascals?
Yes.The amount of gas is determined by its pressure, volume, and temperature. The equation is:PV = nRTwhere:P = pressure, measured in pascals (the SI derived unit of pressure)V = volumen = amount of substance of gas (moles)R = universal gas constantT = temperature
The pressure of 250 kPa acting on 15 cubic meters of a gas at a temperature of 100 K is increased to 500 kPa and the volume is increased to 30 cubic meters?
Use the ideal gas equation to solve this. PV= nRT. You will have to convert your pressure to atmosphere to use the constant R = 0.0821 L*ATM/mol*K. You know your initial pressure, volume, and temperature. Moles can be neglected (n) because they will stay the same. You also know your final pressure and final volume, so you can solve for final temperature.

It depends on the pressure and temperature of the gas.
How many cubic feet of nitrogen are needed to raise the pressure in an 8 inch diameter pipe 400 feet long to 20 psi?
To calculate the amount of nitrogen gas required to raise the pressure in a pipe, we need to follow these steps: 1. Calculate the volume of the pipe in cubic feet. 2. Apply the Ideal Gas Law to determine how much nitrogen is needed to achieve the desired pressure. Step 1: Calculate the Volume of the Pipe The formula for the volume of a cylinder (which is the shape of the pipe) is: V = \pi \times r^2 \times h where: • r is the radius of the pipe (half the diameter), • h is the length of the pipe. Given: • Diameter of the pipe, d = 8 inches, • Length of the pipe, h = 400 feet. First, convert the diameter to feet: d = \frac{8 \text{ inches}}{12 \text{ inches per foot}} = 0.6667 \text{ feet} The radius r is half of that: r = \frac{0.6667}{2} = 0.3333 \text{ feet} Now, calculate the volume: V = \pi \times (0.3333)^2 \times 400 \approx 139.3 \text{ cubic feet} Step 2: Apply the Ideal Gas Law The Ideal Gas Law in terms of volume and pressure is: PV = nRT Where: • P is the pressure, • V is the volume, • n is the amount of gas (in moles), • R is the ideal gas constant, • T is the temperature. To find the additional volume of nitrogen required to increase the pressure to 20 psi, we’ll compare the initial and final states of the gas assuming temperature and the amount of gas are constant. Using the relationship between pressure and volume at constant temperature and gas amount: \frac{P_1 \times V_1}{T_1} = \frac{P_2 \times V_2}{T_2} Since temperature T and n (number of moles) are constant, we can simplify it to: P_1 \times V_1 = P_2 \times V_2 Assuming the initial pressure P_1 is 0 psi (no pressure), the entire volume of the pipe must be filled with nitrogen at the final pressure of 20 psi. Hence, the amount of nitrogen required is equal to the pipe’s volume at that pressure. Thus, 139.3 cubic feet of nitrogen gas is required to raise the pressure in the pipe to 20 psi, assuming no initial pressure.
What are the differences between a vacuum breaker and a SF6 gas circuit breaker breaker and a sf6 gas circuit breaker?
A vacuum breaker uses a vacuum to extinguish the arc when interrupting a circuit, while a SF6 gas circuit breaker uses sulfur hexafluoride gas. SF6 gas circuit breakers can handle higher voltages and currents compared to vacuum breakers. SF6 gas circuit breakers are also more environmentally harmful due to the greenhouse gas SF6, while vacuum breakers are considered more eco-friendly.
What can happen if the gas pressure in SF6 CB is dropped below the specified level?
SF6 is used to increase the dielectric strength of the gap in the circuit breaker. If the gas pressure is too low, the dielectric strength will be inadequate to break the voltage applied across the breaker contacts. This means electricity will continue to arc across the contacts when opened, causing the breaker to heat up and likely fail catastrophically (explode). Most gas breakers have low gas alarms and trip contacts. If there is no way to bypass the breaker, a low gas trip contact can be used to open the breaker before the gas pressure gets too low to allow openning.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.
What is the initial pressure of H2S gas in the flask with a Kp value of 0.120 at 25 deg C?
To determine the initial pressure of H2S gas in the flask, we need the total pressure and the partial pressure of another gas in equilibrium with H2S. Without the partial pressure of the other gas, we can't determine the initial pressure of H2S with just the Kp value and temperature provided.
Is Sodium Hexa Fluoride Gas used in electrical circuit breakers?
yes SF6 gas is used in modern ckt. breaker.
There are 2 grams of H2 gas in a fixed volume container at 273 C. 16 grams of He gas isadded to the container and the temperature is raised to 819 C. So what is the ratio of finalpressure to initial pressure?
The ideal gas law, (PV = nRT), can be used here. The initial pressure is proportional to the initial number of moles, and the final pressure is proportional to the total number of moles. Therefore, the ratio of final pressure to initial pressure is the ratio of the total number of moles of gas at the final conditions to the number of moles initially in the container.
1.00 L of a gas at standard temperature and pressure is compressed to 473 mL What is the new pressure of the gas?
Using the ideal gas law, we can calculate the new pressure of the gas. The initial pressure is 1 atm, the initial volume is 1.00 L, and the final volume is 0.473 L. By applying the formula P1V1 = P2V2, we can solve for the new pressure of the gas after compression.
What is the difference between Air circuit breaker and Vacuum circuiut breaker?
"Air" and "Vacuum" describe how the breaker extinguishes the arcing current. An Air breaker opens far enough that the dielectric strenght of air is enough to extinguish the arc. A vacuum breaker's contacts are in a vacuum. Oil breakers use oil. SF6 breakers use SF6 gas to extinguish the arc.
