The pressure exerted by a fluid in a container depends on the density of the fluid and the vertical distance between the top of the fluid and the point the pressure is measured. The pressure can be calculated as: pressure = (elevation of top of fluid - elevation at point of pressure measurement) x fluid density in your problem if the tank was full, the pressure at the tap would be: pressure = (460 cm + 40 cm) x 1.0 gms/cm3 = 500 gms/cm2 (the density of water is 1.0 gms/cm3) if the tank were nearly empty the pressure at the tap would be 460 gms/cm2 The size and shape of the tank and of the pipe connecting the tank with the tap will not affect the pressure at the tap. This may not seem logical at first, but you could easily come up with an experiment to prove it.
