Apump steadily delivers water through a hose terminated by a nozzle. the exit of the nozzle has a diameter of 2.5 cm and is located 4 m above the pump inlet pipe, which ahs a diameter of 5.0 cm. the pressure is equal to 1 bar at both the inlet and the exit, and the temperature is constant at 20 degrees c. the magnitude of the power input required by the pump is 8.6 kw, and the acceleration of gravity is g= 9.81m/s2. determine the mass flow rate delievered by the pump in kg/s.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
