Calculate the total head loss for water (25°C) flowing at 100 m3/hr. The total flow length is 250 meters and the pipe is 15-cm diameter cast iron pipe. Assume the water enters the pipe through an abrupt (sharp edged) opening, the two gate valves are wide open, the check valve is a swing type and is fully open, the bends are 90 elbows, and flow exits the pipe to a reservoir.
The coal-fired boilder supplies 70 MW to the steam while thermal energy is rejected to a nearby lake whos average temperature is 15 C. What is the minimum required temperture of the boiler to meet the power demands of the city
An electron has an initial velocity with an x component of zero, a y component of 9.35 km/s, a z component 16.1 km/s, and a constant acceleration of 1.60 x 1012 m/s2 in the positive x direction in a region in which uniform electric and magnetic fi..
The casting has a mass of 3Mg. Suspended in a vertical position and initially at rest, it ia given an upward speed of 200mm/s in o.s^s using a crane hook H. Determine the tension in cables AC and AB during this time interval if acceleration is con..
