you are a client asked an architect to design a villa for yourself. You as a client didn’t ask for fees. The architect finished design and tried to collect the fees, and you were reasonable thinking that the fees will be around $3000. Since, this was paid for similar villa design of your friend. The architect argued that the fees should be $5000, discuss the possible action by judge if architect sued you and explain why?

The velocity field of a permanent, incompressible and isothermal flow is given by u = a (x^2 - y^2) (1) v = −2axy (2) w = 0 (3) Gravitational acceleration acts on the z axis only. a) Write the Navier-Stokes equations for this flow, canceling the appropriate terms and replacing the non-zero derivatives with their detailed expression. Be sure to indicate clearly your assumptions. (4 points) b) From the result obtained in (a), demonstrate that the pressure field is continuous and therefore physically possible (2 points) c) Get the expression for the flow pressure field (4 points)

Why did king Henry VIII of England break with the Roman Catholic Church? Make sure to also list and explain the legislations that were approved under Henry VIII by the English Parliament that officially split the Church of England from the Catholic Church. Under Henry, was the Church of England dramatically different from the Roman Catholic Church?

1. The turbine of a hydrostatic plant is driven by a falling
head of water from a falling head of water from a source 30 m high
up through a 600 mm penstock flowing full.
A. Evaluate the theoretical velocity of water as it hits the
turbine blades in m/sec.
B. Evaluate the theoretical discharge of water in
m3/s.
C.If the turbine is only 70% efficient, estimate the horsepower
available from it..
2. Reservoir A supplies water to a nozzle having a diameter of
80 mm which is discharge water 40 m below the reservoir water level
at a velocity of 24m/s
A. Determine the loss of head in the pipeline.
B. Determine the horsepower produced by the jet.
C. Determine the efficiency of the nozzle.
3. The diameter of a pipe carrying water changes gradually from
150 mm at A to 450 mm at B. A is 5 m lower than B. If the pressure
at A is 70 kPa and at B is 50 kPa when 150 liters/ sec is
flowing.
A. Determine the direction of flow
B. Determine the frictional loss between two points
4. Reservoir A and B have elevations of 100 m and 160 m respectively. A pump is installed near reservoir A to pump the water from A to B. The rate flow in the pipe is 650 liters/sec. If the head loss in the pipeline is 8.22 m, compute the horsepower required to pump the water to B.
5. A reservoir A contains water at an elevation of 45 m and a 50 mm pipe line leads downhill from the reservoir and discharges into air at B at an elevation 0. If the loss of head between the reservoir A and B is 43.5 m compute the discharge flowing in the pipe.
6. A turbine is located at an elevation 200 m below that of the surface of the water at intake. the friction loss in the pipeline leading to it is 8 m and the turbine efficiency is 90%. What will be the power delivered by the turbine if the flow is 3 m3/ sec in kW?
7. Water is discharged through a nozzle having a diameter of jet
100 mm at a velocity of 60 m/s at a point 240 m below the
reservoir.
A. Compute the total headloss.
B. Compute the horsepower produced by the jet.
C. Compute the power lost in friction.
