An Open-Tank contains Glycol. A connection tube connects a pressure gauge to a point 2 feet from the bottom of the tank. The maximum height of Glycol in the tank is 10 feet The Open-Tank is vented to the atmosphere at the top. Assume that the density of Glycol is 1036kg/m3 , density of water = 1000kg/m3 , 1' =0.3048m, 1 Pa = 0.000145 psig, and g = 9.8m/s2.

2. Calculate showing steps and stating any assumptions the Span of the Pressure Gauge in psig.

3. Calculate, showing steps and stating any assumptions, the reading of the Pressure Gauge in Pa if the Open-Tank is 40% full

A Continuous Hydrometer measures the density of Sunflower Oil. The density of Sunflower Oil varies between 800kg/m3 to 900kg/m3. The Continuous Hydrometer is calibrated such that when the density is minimum, the Output Voltage is 0.1V and when it is maximum, the Output Voltage is 5V. Assume that temperature and humidity remain constant. Sunflower Oil is supplied in 150L Barrels. An empty Bottle weighs 100kg.

4. Calculate showing steps and stating any assumptions the mass of a Barrel of Sunflower Oil in kg when the Voltage Output is 5V.

5. If the Specific Gravity of Sunflower Oil was measured to be 0.9, what was the Voltage Output?
