$(15\%)$ The water flow rate through the siphon is $6\frac{L}{s},$ the room temperature is $30C,$ and the pipe diameter is $30mm.$ Please answer the following questions:

$($a$)$ Please calculate the tube outlet position, comparing with the water free surface in the tank.

$($b$)$ Compute the maximum allowable height $h,$ so that the pressure $A$ is still above the vapor pressure of the water $P_v=4\mathrm{.}25$kPa at $30C.$ The atmosphere pressure is assumed to be $100$kPa.
