A working fluid enters a steady flow system with a velocity of 30m/s and leaves at 140m/s. The mass flow rate is 9 kg/s. The properties of the fluid entry are 13.8 bar,

0.122 m3

/kg, and internal energy 42.2 kJ/kg, and exit properties are 1.035 bar, 0.805

m3

/kg and internal energy 208 kJ/kg. Determine the work transfer in kW from the

system

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

i already answered it by 34/s

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
