Answer #1

1 lb=0.453592 kg

1 ft=0.3048 m

answer , power =2259.6  watt

avenge power needed, P : - pa mgh m mass of lifting object ha Distance, t time taken. m2 250 1b = 113. 398 kg. h=4ft = 1.22m ,g=9.8 m/s p = 9.8% 1122 113.4 x 0.6 p=2259.6 W unit - Watt

James Watt once observed that a hard-working horse can lift a 330 lb weight 100. ft in 1 minute. Assuming the horse generates energy to accomplis this work by oxidatively metabolizing glucose C6H12O6(s) + 6 O2(g)----> CO2(g) + 6 H2O(l) ΔGo = -2880 kJ and that only 40% of the chemical energy can be converted to work, calculate how much glucose the horse must metabolize to sustain this rate of work for one hour at 298 K.

A mass weighing 4 pounds is attached to a spring whose constant is 2 lb/ft. The medium offers a damping force that is numerically equal to the instantaneous velocity. The mass is initially released from a point 1 foot above the equilibrium position with a downward velocity of 12 ft/s. Determine the time at which the mass passes through the equilibrium position. (Use g = 32 ft/s2 for the acceleration due to gravity.) s Find the time after the mass...

Exhaust gas from a power plant passes through a 15- by 20-ft rectangular duct at an average velocity of 50ft/s. The total length of duct is 250 ft, and there are two 90o bends. The gas is at 180oF and about 1 atm, and the properties are similar to those of air. Calculate the pressure drop in the duct and the power required to overcome pressure losses.
