The only one way that heat can move is: From
higher temperature
to lower temperature, never the other way.
Examples:
-- When you put an ice cube into a glass of warm soda, heat never moves
out
of the ice cube into the soda, making the soda warmer.</span>
-- When you mix cold water with warm water, heat never moves out of the
cold water into the warm water, causing ice to appear and the warm water
to get warmer.
-- When you blow your breath across a spoonful of hot soup, the soup
never draws heat out of your breath, chilling your breath and boiling the
soup on the spoon.
-- When you step into a warm steaming bubble bath, heat never moves
from your body into the hot bath, causing your tootsies to shiver and the
bath to get even hotter.
Power = work/time = (Force times distance)/time
= (30N *10.0m)/5.00s = 300/5 = 60 Watts
3-m-high large tank is initially filled with water. The tank water surface is open to the atmosphere, and a sharp-edged 10-cm-diameter orifice at the bottom drains to the atmosphere through a horizontal 80-m-long pipe. If the total irreversible head loss of the system is determined to be 1.5 m, determine the initial velocity of the water from the tank. Disregard the effect of the kinetic energy correction factors.
