Automobile Pump power using energy equation

Please give me some feedback on this problem - Gasoline is pumped from the gas tank of an automobile to the carburetor through a 10 ft long, 1/4" diameter fuel line of steel tubing. The line has five 90 degree smooth bends with r/d of 6. The gasoline discharges through a 1/32" diameter jet in the carburetor to a pressure of 14 psia. the pressure in the tank is 14.7 psia. If the pump is 80% efficient, what power must be supplies by the pump if the automobile is accelerating and consuming fuel at the rate of 0.1 gal/min.? Thanks

Finding Vertical Distance in Pipe Line System

Any help on this would be much appreciated! Thanks!For the system in attachment, calculate the vertical distance between the surfaces of the two reservoirs when water at 10 degrees celcius flows from A to B at the rate of 0.03 m^3/s. Both pipes are cast iron and the elbows are standard. The total length of the 3" pipe is 100 meters. For the 6" pipe, it is 300 meters.

2 small problems involving Head loss and fluid flow

In figure 2. if Headloss 1->2 = 3 ft and headloss 2->3= 2ft find the velocity at point 2. Figure 3 is attached as well and written.

Bernoulli's equation

IN figure 2 the cross sectional area at point 1 ia 5"^2 and at point 2, it's 10"^2. If the pressure at point 1 is 100 psi and the friction loss between the two points is 30 ft. find the pressure at point 2. Q=100gpm = constant 1 gal water=321"^3 jw=62.4 lb/ft^3

Bernoulies equation

A venturi has a large section diameter of 4', where the velocity V1=20ft/sec. The pressure difference between this section and throat, (P1-P2) = 25 psi. If the fluid is sea water (Sg=1.03) what is the diameter of the throat? Use figure #3 attached
