The tank is insulated. When the water is hot, immersion heater switches off. Compared to a tank with no insulation, the rate of energy transfer from water in an insulated tank is?

What happens in a global convection cell

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
