Aship 90 meters long is floating on an even keel at 6 m draft. the half-ordinates, commencing from forward, are as follows: 0, 4.88, 6.71, 7.31, 7.01, 6.40, and 0.9 m respectively. the half-ordinates 7.5 meters from bow and stern are 2.13 and 3.35 m respectively. the change in draft if 153 tonnes of cargo are loaded with its center of gravity vertically over the center of flotation. find the water plane area (wpa); and lcf from the aft perpendicular.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
