An undersea camera (Figure 5.36) is to hang from a float in the ocean, allowing it to take constant video of undersea life. The camera is relatively heavy; it weighs 40 pounds and has a volume of only 0.3 ft3. It is to hang 2 ft below the float on a pair of wires, allowing it take video at this constant depth. The float will be cylindrical, have a specific gravity, sg = 0.15, have a thickness of 6 in. What is the minimum diameter of the float? Note that for the minimum float, the waterline will be coincident with the top of the float. If the float is made of a larger diameter, what will happen? If the float is made of a smaller diameter, what would happen? FIGURE 5.36 6 in 2.

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

An undersea camera (Figure 5.36) is to hang from a float in the ocean, allowing it to take constant video of undersea life.
The camera is relatively heavy; it weighs 40 pounds and has a volume of only 0.3 ft3. It is to hang 2 ft below the float on a
pair of wires, allowing it take video at this constant depth. The float will be cylindrical, have a specific gravity, sg = 0.15,
have a thickness of 6 in. What is the minimum diameter of the float? Note that for the minimum float, the waterline will be
coincident with the top of the float. If the float is made of a larger diameter, what will happen? If the float is made of a
smaller diameter, what would happen?

A balloon is surrounded by a tank of liquid at negative pressure and is con- nected to the atmosphere by a tube of length L and cross-sectional area A (Fig. 7.25). The pressure inside the balloon p oscillates above and below atmospheric pressure causing small changes in the balloon volume V. The elasticity of the balloon is characterized by its compliance C, defined by Ap = AV/C (a) Derive a second-order differential equation for AV(t), assuming that (i) the pressure differential along the tube accelerates the air in the tube and is not used to overcome entrance, exit, or tube losses; and (ii) the air density p is constant. From the equation, show that the natural frequency of the system is JA/pLC.

State Pascal’s principle and give one application of the principle. An object is dropped into a beaker of water. Two forces are operating on the object viz. the weight of object and the buoyant force FB due to the fluid. Explain, in terms of the forces when the object. a.) Sinks to the bottom of the beaker b.)Floats in the water A hydraulic press for compacting powdered samples has a large cylinder with a diameter of 10.0 cm and a small cylinder of diameter 2.0 cm. If a force of 350 N is applied to the small cylinder, what will be the force exerted by the fluid on the large cylinder? Be consistent with your units.
Solve 1st problem
QV: a hydraulic press is used to compact powdered samples. The device is made of two interconnected cylindrical chambers filled with oil if density psubscripto anc closed by two pistons. The small chamber on the right has diameter d and the large chamber on the left has diameter 5d. A lever is attached to the piston pushing down on the fluid in the small cylinder. The horizontal lever is hinged on the left, at distance L from the small piston, and a force of magnitude Fsubscript0 is applied vertically down at distance 2L from the hinge (Fig.5). You may assume that the lever and pistons have negligible mass. a. Determine the magnitude of the force Fin that the small piston exerts on the fluid in the small cylinder. Hint: you may consider that the lever is at rest in the horizontal position. b. Determine the pressure change applied to the fluid by the small piston. c. Determine the magnitude Fout of the force that the fluid applies to the large piston.
