Determine the total force, in kN, on the bottom of a 100 A 50 m swimming pool. The depth of the pool varies linearly along its length from 1 m to 4m. Also, determine the pressure on the floor at the center of the pool. In kPa, the atmospheric pressure is 0.98 bar, the density of the water is 998.2 kg/m3. And the local acceleration of gravity is 9.8 m/s2.

A certain u-235 fueled pressurized water reactor is just critical. Suddenly the average coolant temperature falls from 300c to 280c \alphat=-0.0001 \deltak/c. How much reactivity is inserted? What is the new value of keff?
Air is flowing steadily through a horizontal tube at a constant temperature of 32 deg C and a mass flow rate of 1 kg/s. At one point upstream where the tube diameter is 50 mm, the pressure is 345 kPa. At another point downstream the diameter is 75 mm..
compare it with efficiency of an otto cycle operating with the same maximum pressure?
A piston/cylinder system contains superheated vapor initially at 400C and 600 kPa. The system is cooled at constant pressure by exchanging heat to the surroundings until the cylinder contains only saturated liquid. The surroundings are at 25C.
