Water is being pumped from bottom of a well 15ft deep at the rate of 200gal/he into a vented storage tank to maintain a level of water in a tank 165ft above the ground. to prevent freezing in the winter a small heater put 3btu/hr into the water during its transfer from the well to the storage tank, assuming that the well water is at 35fahrenhiet? a 2-horsepower pump is being used to pump the water . about 55% of the rated horsepower goes into work of pumping and the rest is dissipated as heat to the atomsphere.

What precautions should you take to prevent injuries when dealing with heavy loads?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
