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.

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point. the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.

What is the main objective of using reheat rankine cycle?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
