Question

Find the work in ft-lbs required to empty a full hemispherical tank w/ a radius of 6 ft by pumping the water to 2 ft above the top of the tank

Answer 1

So you need to set up an integral here, any ideas on how to get started? Really try to break it down into the simplest things you know. What is the definition of work? Draw a picture that describes this scenario and label everything you possibly can and list out variables with their units. I'll help you along but I want to only help you get there with me doing as little as possible so that you more fully understand what you know and that you truly understand what's going on so that you can do it on your own later, and hey, possibly even help others as well! =P

Answer 2

ok, where can we start?
