Question: A pressure-reducing valve is set to limit the force exerted by a clamping cylinder. The 1.5-in. bore cylinder must not exert more than 2900 lbf to prevent damage to the part being held. At the moment the DCV is shifted to close the clamp cylinder, the supply pressure is 2750 psi.
a. What pressure drop must the pressure reducing valve maintain?
b. If the flow to the clamp cylinder is 8 GPM, what orifice coefficient (k) must be developed by the pressure reducing valve?
An aluminum cup contains 225 g of water and a 40-g copper stirrer, all at 27°C. A 400-g sample of silver at an initial temperature of 88°C is placed in the water. The stirrer is used to stir the mixture gently until it reaches its final equilibriu..
