Equation 19.9, for the thermal shock resistance of a material, is valid for relatively low rates of heat transfer. When the rate is high, then, upon cooling of a body, the maximum temperature change allowable without thermal shock, ΔTf, is approximately where σf is the fracture strength. Determine ΔTf for glass, soda-lime. The values for modulus of elasticity, tensile strength, and coefficient of thermal expansion are 69 GPa, 69 MPa, and 9 x 10-6 °C-1 respectively. Enter your answer in accordance to the question statement 111111.111 °C

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
