The given diagram shows the water tank and the position of the shower head in the bathroom of a household. The water pressure must be 8 kPa in order to function shower head effectively. The density of water is 1000 kg `m^(-3)`. Find the minimum height that a plumber must raise the water tank to, so that the water pressure at the shower head can be 8 kPa. (Assume pipe of sufficient length is given.)
