1. A well-type inclined manometer has a gas pressure difference of 7.5 cm of water coluna applied to its ports (higher pressure to well). If the manometer is at an angle of 7.5° am contains a fluid with a density of 0.8 g/cm3, what is the reading R?
2. Consider the standard chromel-alumel thermocouple circuit shown in the Figure
(a) Find the voltage measured by the DVM.
(b) If the DVM measures 17.51 mV, what would the temperature T1 be?
3. A sling psychrometer gives dry-bulb and wet-bulb readings of 80°F. What is the relative humidity?
4. A sling psychrometer has a dry-bulb reading of 30°C and a wet-bulb reading of 15°C. Find the relative humidity and the humidity ratio.
