Please answer all parts
Round your final answers to two decimal places. A pump increases the water pressure from 70 kPa at the inlet to 700 kPa at the outlet. Water enters this pump at 15°C through a 0.8-em-diameter opening and exits through a 3.5-cm-diameter opening. Determine the velocity of the water at the inlet and outlet when the mass flow rate through the pump is0.58 kg/s Vinlet m/s m/s exit What is the velocity at the inlet if the...

4. An old, rough-surfaced, 2-m-diameter concrete pipe with a Manning coefficient of 0.025 carries water at a rate of 5.0 m'/s when it is half ful. This pipe is to be replaced by a new smooth pipe with a Manning coefficient of 0.012. Determine the diameter of the new pipe if it also is to flow half full with a flow rate of 5.0 m'/s Water initially flowing in the horizontal section of pipe of diameter 12.00 cm shown in...

just now i sent this questions.
this is the answer given. however the answer i afraid
that he used formula that is not for constant surface temperature
and noncircular formula.
this is the formula foe the noncircular tube. because
the question ask about triangle.
my problem is, i cannot answer question 1(b) that ask
the heat transfer coefficient, h. please help me. thank you.
