What is the head loss for water flowing through a horizontal pipe if the gage pressure at point 1 is 1.05 kPa, the gage pressure at point 2 downstream is 1.00 kPa, and the velocity is constant?

The required head loss is 0.00509 m.

Explanation:

Head loss for horizontal pipe  (zout − zin) with no pump (hs = 0), and constant cross section  (Vout =Vin) is given by:

                  Head loss=                     ( for constant velocity)

where,

 = pressure at point 1.

= pressure at point 2.

d= density of water flowing

g = acceleration due to gravity

Now,

                                             Head loss =

                                                              = 0.00509 m

Hence the head loss is 0.00509 m.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
