A venturi meter, shown in the figure, has the geometric characteristics supplied below, m³ a volume flow rate of 0.01 of a fluid with density p 874 flows through it, the S kg differential manometer fluid is mercury with density 13,600 Find the height h of the manometer in meters. Assume acceleration of gravity 9.80 m³ m 8² D1 Diameter of section 1= 0.123 m D2 Diameter of section 2= 0.06 m h 1 2 J . Flow direction indicated by blue arrow

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
