HELP on a spacecraft mission to saturn for the injection velocity i beg you please
on intial approach to Saturn, the spacecraft mass is 3500 kg. To enter orbit around Saturn , the vehicle has a 400N thrust primary propulsion engine, with a specific impulse of 310 sec...
question 3 part b ( see attachment)
The Attempt at a Solution
the answer should be 10.98v for Vth (thevenin equivalent voltage)
all my attempts were unsuccessfull.
I found voltages such as 22.2 volts
i think I lake...
fluid is flowing upward through a 1cm diameter pipe at 0.15m/s find the necessary power per unit length to drive the flow through the pipe.
flux of momentum out - flux of momentum in= forces acting on the CV (tau( downward)...

Q.4 An incompressible fluid of density ρ flows steadily through a two-dimensional infinite row of fixed vanes,
a few of which are shown below. The vane spacing is a. The velocities V1 and V2 and pressures p1 and p2
are all constant along their respective stations, (1) and...
a vertical, 1cm-diameter jet of water impinges upon a bathroom scale such that the latter exhibits a reading of 5 kg. Estimate the volume flow rate of the jet.
Q(volume flow rate)=U*A(area where the jet of water is applied on)
ok here is what I did but did not get the right answer.
mass of water = density of water x volume of water in the tank= 1000(kg/m³)*3.53(m³)
=3530 kg note : I did this as if the tank was fully filled with water but it is not.
mass of tank= total mass ( tank + water) minus mass of water. you...
2.mass of water:( 55kN-weight of tank)/9.81
3. total mass of truck+water=55kN/9.81=5606.52 Kg
4.mass of empty tank= 5606.52 Kg-mass of water
5.mass of alcohol= 2785.17 Kg( in a tank full of alcohol)
note 2 and 3 are the same equations which leads to 0=0.
A cylindrical tank of internal diameter 1.5m and length 2.0m is mounted on a trailer. When the tank is filled with water the combined weight is 55 kN. Find the weight of tank plus trailer with the tank full of methyl alcohol (relative density 0.789).
