(4) Water is being syphoned out of a pool of plan area A=100 m². The hose goes from the bottom ofthe pool over a fence of height H=1.8 m (above

the top of the pool) and into a drain with the hose outlet (free jet) h=1.5 m below the base of the pool. The pool is initially full at a depth ofD=3 m and the hose diameter is d=3 cm. Calculate a. The initial flow rate through the hose b. The minimum pressure in the hose while the pool is draining and its location c. The temperature at which the water boils in the hoseС.
