SallySue (BillyBob's long suffering wife) is watering the goats in the back 40 acres, and has to cobble together a couple of old garden hoses to make the distance from her outside water tap. Assume that the ground is perfectly flat and there is no change in elevation. Yes, Billy Bob and SallySue Huckaby live on a flood plain and get flooded out regularly. But I digress. Connected to the tap, there is a 2.00cm-d hose, and that is connected to a 3.00cm-d hose which reaches the water trough for the goats. Assume that the holes in the pipe have been properly mended with duct tape so there are no leaks. If it takes 2.50minutes to fill up the 20.0gallon water trough (old bathtub), determine the difference in pressure between the second hose and the first.

1)  A plot of pump net head is shown below. Two curves are drawn: blue color curve and red color curve. Which one is called pump performance curve? Will the location of pump performance curve change if the velocity of the fluid at pump outlet changes? a) red curve; No, the location will not change b) blue curve; yes, the location will change c) red curve; yes, the location will change d) blue curve; No, the location will not change 2) In a turbine system, states A and B are homologous. If the net head ratio HA/HB =16 , volume flow rate ratio VA˙/VB˙=9. What is the diameter ratio DA/DB ? a) 3/2 b) 6 c) 12 d) 2/3

Please explain all intermediate steps. Thanks you

A gardener feels it is taking too long to water a garden with a 0.40 in. diameter hose. By what factor will the time be cut using a 0.53 in. diameter hose instead? Assume nothing else is changed.

Determine the % increase in Flowrate, Net pumping head and Pump power based on the following conditions below: a) Increasing the impeller speed by 30% b) Increasing the impeller diameter by 20% c) Compute the same if the two conditions above will prevail in one condition Please show complete solution.

Calculated a) as 16.554kN, b) as 26.003kN and c) as 0.637m Need help with d) and e)
