Q// Upon completion of the Reynolds experiment, we had this information. The tube diameter was 0.03 m, the flow rate 21*10^-6 Q (m ^ 3 / s) and the lamellar bisection type 'Find Re, viscosity and velocity m / s at a temperature of 26 ° C for water.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.

For a gate width of 2 m into the paper, determine the force required to hold the gate abc at its location.
