What else can I help you with?
When a sealed bulb containing gas is immersed in an iced bath it has a gas pressure of 345 torr When the same bulb is place in an oventhe pressure of the gas rises to 745 Torr calculate the ovens temp?
The absolute temperature of the oven is 745/345 times the absolute temperatureof the ice bath.(745/345) x (273.15 K) = 589.85 K = 316.7° C.
Why does a bulb make a bang when broken?
When a light bulb breaks, the sudden release of internal pressure causes the glass to shatter, creating a loud bang. The pressure is due to the gases inside the bulb, such as argon or nitrogen, that rapidly expand as the glass breaks.
How do you get amperes of 25 watts bulb?
To calculate the amperage of a 25-watt bulb, you need to divide the wattage by the voltage at which the bulb operates. For example, if the bulb operates at 120 volts, you would divide 25 watts by 120 volts to get the amperage.
Why does water does not run out of dropper unless the rubber pulp is pressed?
Water does not run out of a dropper unless the rubber bulb is pressed because when the bulb is squeezed, it creates a vacuum inside the dropper. This vacuum pressure forces the water to be sucked up into the dropper. When the pressure is released by letting go of the bulb, the water remains in the dropper due to the lack of pressure forcing it out.
How do you calculate the difference between a dry bulb and a wet bulb?
To calculate the difference between a dry bulb and a wet bulb temperature, you measure both temperatures using a thermometer. The dry bulb temperature is the ambient air temperature, while the wet bulb temperature is measured with a thermometer that has its bulb moistened with water. The difference between these two temperatures indicates the level of humidity in the air; a larger difference suggests lower humidity, while a smaller difference indicates higher humidity. This calculation is often used in meteorology and HVAC applications.
What is the dew-point when the dry bulb temperature is 20C and the relative humidity is 17?
To calculate the dew point, first calculate the vapor pressure: 17% of the saturation vapor pressure at 20°C (17% × 2.338 kPa), which equals 0.397 kPa. This vapor pressure corresponds to a dew point of about 6.1°C.
What are the importance of pressure bulb?
The Zone in a loaded soil mass bounded by any arbitrary isobar is known as a pressure bulb. The vertical pressure at any point on the surface of the pressure bulb is the same.
What is the relative humidity if dry bulb temperature is 25 degrees Celsius and wet bulb temperature is 22 degrees Celsius?
To calculate relative humidity using the dry bulb temperature (25°C) and wet bulb temperature (22°C), you can use a psychrometric chart or the following formula: Relative Humidity (RH) = (Actual Vapor Pressure / Saturation Vapor Pressure) × 100. The saturation vapor pressure at 25°C is approximately 3.17 kPa, and the actual vapor pressure can be derived from the wet bulb temperature. Using this information, the relative humidity is found to be around 73%.
Pressure bulb can you use a sodium bulb in a mercury fixture?
no
Why does the qater in a dropper not come out unless rubber bulb is pressed?
The water in a dropper does not come out until the rubber bulb is pressed because of the difference in air pressure. When the bulb is in its relaxed state, the pressure inside the dropper is lower than the atmospheric pressure, keeping the liquid inside. Pressing the bulb increases the internal pressure, forcing the liquid out through the nozzle. When the bulb is released, the pressure equalizes, preventing the water from flowing back in.
How do you calculate how hot a light bulb is?
To calculate the temperature of a light bulb, you can use the Stefan-Boltzmann law, which relates the temperature of an object to the amount of radiation it emits. You would need to measure the power output of the light bulb and its surface area to calculate the temperature. Keep in mind that the temperature of a light bulb can vary depending on factors like the type of bulb and how it is being used.
How do you calculate the gage pressure of a system?
To calculate the gauge pressure of a system, subtract the atmospheric pressure from the absolute pressure of the system. Gauge pressure Absolute pressure - Atmospheric pressure.
How do you calculate gauge pressure in a system?
To calculate gauge pressure in a system, subtract the atmospheric pressure from the absolute pressure within the system. Gauge pressure Absolute pressure - Atmospheric pressure.
How do you calculate dry bulb temperature and wet bulb temperature to get relative humidity?
To calculate relative humidity, you first need to determine the dry bulb temperature (DBT) and the wet bulb temperature (WBT) using a psychrometer. Once you have these temperatures, you can use a psychrometric chart or a formula that incorporates both temperatures. Relative humidity (RH) can be calculated using the equation: ( RH = \frac{E}{E_s} \times 100 ), where ( E ) is the actual vapor pressure derived from the WBT and ( E_s ) is the saturation vapor pressure derived from the DBT. Alternatively, many online calculators can compute RH directly when provided with DBT and WBT.
How do you calculate differential pressure in a system?
To calculate differential pressure in a system, subtract the lower pressure from the higher pressure. This difference indicates the pressure change across the system.
How you calculate pressure?
Pressure = Force / Area
How to calculate pressure in a pipe?
To calculate pressure in a pipe, you can use the formula: Pressure Force / Area. This means that pressure is equal to the force applied divided by the cross-sectional area of the pipe. By knowing the force and the area, you can calculate the pressure within the pipe.
