Question: An aluminum block receives heat from two different sources: 10 kW from a source at 1000 K and 5 kW from a source at 500 K. It loses heat to atmosphere at 300 K. Assuming the block to be at steady state,
a) Determine Qdot. (kW) b) Determine the rate of entropy generation in the system's universe. (kW/K)
A re-supply satellite is launched from NASA/Wallops Island into a circular orbit of radius 6678 km with inclination of i = 38. In order to rendezvous with the ISS, the re-supply satellite needs to both raise it's altitude to 400 km, via a Hohmann tra..
Aluminium has a density of 2.7 g/cm3. Suppose you would like to produce a composite material based on aluminium having a density of 1.5 g/cm3. Design a material that would have this density. Would introducing polyethylene, with a density of 0.95 g/cm..
Determine the maximum permissible value of the load q if the allowable bending stress in the shelf is σallow= 7.5 MPa and the position of the supports is adjusted for maximum load carrying capacity.
An internally pressurized section of round steel tubing is subjected to tangential and axial stresses at the surface of 200 and 100 MPa, respectively. Superimposed on this is a torsional stress of 50 MPa. Make a Mohr circle representation of the s..
the hull of a boat has a volume of 150 m3 and the total mass of the boat when empty is 8560 kg. determine how much load
What is the total area of the collectors required to satisfy the need of having the swimming pool always at least at 28? C? Given that each collector is about
An electric motor converts electricity to rotating shaft work with an efficiency of 54%. The rotating shaft turns the impeller in the pump which, in turn, increases the pressure of the water (i=1000kg/m3) by 200 kPa. If the motor is consuming 3.5 kW ..
Obtain the general expression for the path length and find the extremal that satisfies the end conditions ρ(-π/2) = ρ(π/2) = a.- Verify that this extremal is the same as the shortest path that would be obtained by developing the cone on to a plane.
Derive the energy change when a cube-shaped powder of edge l is densified without grain growth. From the calculated energy change, discuss conditions to improve sinterability. The specific surface energy of the powder is γs and the specific grain ..
Different measurement points the same? If they are not the same then why not? In your opinion, what may be the cause of this misalignment?
the 0.78 kg bob of a pendulum is fired from rest at position a by a spring which has a stiffness of k 1.62 knm. the
