2) A water tank is schedule for maintenance. To do that, the water inside the tank need to be emptied through the drain pipe. The total water leaving the tank can be expressed by Equation 1. (Eq.1) dr Estimate the time to empty the tank using suitable numerical method. H(t) (ft) is the water level at a time t (sec), D = tank diameter (12 ft), d= drain pipe diameter (1/12 ft) and g= gravitational acceleration (32.2 ft/sec). The initial water level, H, 1 ft. How accurate your estimation with the real answer? (hint: calculate the error). 2H Check with the real answer: tempty
