How does an accelerometer work?

A centrifugal Blower delivers 6m^3 of air per second against a head of 55mm of alcohol of relative density 0.79 when running at 400 RPM. Calculate the power required if the efficiency os 0.7.

The pulley has mass 12.0 kg, outer radius Ro=250 mm, inner radius Ri=200 mm, and radius of gyration kO=231 mm. Cylinder A weighs 71.0 N. Assume there is no friction between the pulley and its axle and that the rope is massless.

The air standard efficiency ofan Otto cycle compared to diesel cycle for thie given compression ratio is: (a) same (b) less (c) more () more (d) unpredictable (d) e) more or less depending on power rating

Consider two identical rooms: one with a 2-kW electric resistance heater and the other with two couples fast dancing.

Water enters a circular tube whose walls are maintained at constant temperature at specified flow rate and temperature. For fully developed turbulent flow, the Nusselt number determined from Nu - 0.023 can be law of cooling in this case is Re0.8 PrO.

16 Suppose that a steel of eutectoid composition is cooled to 550°C (1020°F) from 760°C (1400°F) in less than 0.5 s and held at this temperature.

The rotor in a shaded pole motor consists of A coils energized by alternating current B a short circuited loop of copper wire c a permanent magnet D an iron cylinder
