The power source in a particular welding setup generates 3119 watts that can be transferred to the work surface with a heat transfer factor of 0.65. The metal to be welded is low carbon steel. The melting factor in the operation is 0.4. A continuous fillet weld is to be made with a cross-sectional areas of 20 mm2. Determine the travel speed in mm/s at which the welding operation can be accomplished. Hint: See Table 28.2 for the melting temperature of low carbon steel.

The power (in watts) used to move air out of the lungs is equal to the air pressure (in N/m2) multiplied by the air flow rate (in m3/s). For quiet breathing (where p = 100 N/m2 and flow rate = 100 cm3/s or 1.0 x 10-4 m3/s), the power involved = 0.01 W ; for loud singing (where p = 4000 N/m2 and flow rate = 400 cm3/s or 4.0 x 104 m3/s), the power involved = 1.6 W. In...

We have to calculate the value of Power of an electric DC motor IN WATTS made from scratch. The only known values that we have are: The Voltage (V) which is 9V and the current (I) that we are using which is 3 A, also the value of "n" which is n= 90.16 m (the number of turns of the wire used in the motor) I already asked here for this problem and someone answered this: Voltage = 9 V,...
