E)Purely resistive loads of 24 kW, 18 kW, and 12 kW are connected between the neutral and the red, yellow and blue phases respectively of a 3-Φ, four-wire system. The line voltage is 415 V. Calculate: i. the current in each line conductor (i. e., IR, IY and IB); and
ii. the current in the neutral conductor.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
