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 this boat can carry without sinking (a) in a lake and (b) in seawater with specific gravity of 1.03.
Determine the minimum thickness of fibreglas insulation that needs to be used in the wall in order to avoid condensation on the outer surfaces.
SEM212 - Aim of this demonstration is to use measurements of the load required to propagate a crack (tear) in packaging tape to determine its fracture toughness.
However, even when the cylinder is pressurized, the torque T is still sufficient to keep the seam closed so that no water leaks out. Determine the angle theta degrees that requires the minimum torque T to keep the seam closed. (Hint: use Mohr's ci..
Determine the rate of heat loss from the molten salt per meter length of the pipe.
A gear blank has been successfully hot forged on a mechanical press in a closed die. At the beginning of a new production run
In a refrigerator 1 kW is removed from the -10 degree C cold space and 1.3 kW is moved into the 30 degree C warm space. Find the exergy fluxes including direction associated with the two heat transfers.
your job is to create a design of Rankine cycle that create the most possible power from this heat source . you may use any working fluid for which you can find the properties , assume the turbines 92% efficient and pumps 85%
A hemispherical dome is filled with water. The dome arrangement weighs 28kN and is fastened to the floor by bolts equally spaced
Water drips at the rate of 5 drops per second from a leaking tap. Determine the vertical distance between two consecutive drops after the lower drop has attained a velocity of 3 m/s.
Evaluate thermal efficiency of the cycle
In the idealized model attached shown, m = 15 kg, k = 135 N/m, and the viscous damping ratio is 0.15. Assume that an external harmonic force F(t) = 15 cos 4 t acts on the system with F0=15 N and forcing frequency of 4 rad/s.
