A launch approaches a wharf at a speed of 10.5 knots(=5.4m/s).The engine are put in the reverse when the launch is 10 m from the wharf, the retardation being 1.25m/s squared. will the launch come to rest before hitting the wharf.. If not, with what velocity will it strike the wharf.
8 x product engineering and design review (week 2 – 12), ~3 pages per item which must contain a brief description of the product then delve into concepts such as materials selection, manufacturing methods, life cycle analysis, recyclability and overa..
A 4 m diameter sphere is embedded in insulation. The sphere contains a liquid-ice mixture maintained at 0 deg C. The ambient temperature surrounding the insulation is 25 deg C.
(a) Find the rate of heat transfer (kW) to the water. (b) Draw a schematic of the system. (c) Determine the air outlet temperature (°C)
No heat interactions with the environment are allowed. You do not need to describe the details of the process that produces the maximum work, but you do need to describe the final state of the blocks fully.
Calculating the mechanical properties of unidirectionally reinforced composites
Determine the specified data for water at the states indicated and locate each state on a P-v and T-v diagram.
Find the capacity of a cylindrical tank that is 250 feet in diameter and 30 feet high? In the above problem, what is the capacity if the tank is 75% full, and what is the capacity in gallons?
Water is being pumped from a large lake to a reservoir 30 m above at a rate of 5x10-3 m3/s by a 12 kW (shaft) pump. If the irreversible head loss of the piping system is 8m, determine the mechanical efficiency of the pump.
The heating is to be done in a mixing tank by direct injection of the steam, all of which condenses. Determine the two inlet mass flows needed to meet the desired hot water flow rate.
A 50 hp motor with an efficiency of 0.80 is to be replaced by a newer model motor with an efficiency of 0.90. The motor is expected to operate 3000 hours per year. The cost of electricity in our area is $0.06 per kWhr.
Construct a suitable finite element model and compare the FEA predictions with the theoretical data and produce a graph to show the stress distribution
The mean diameter of a conical friction clutch is 250mm with a width of the conical surface being 50mm. The clutch is lined with a material having a coefficient of friction of 0.25
