the equation for rate of heat flow is
Q/t = kA del T/x
Q= kA del T* t/x
= 0.81 (0.81(0.38))(17+273)(0.0166666667 minutes)/0.53* 10^-2
Q/ min =227.36 J/min

A glass window 0.53 cm thick measures 86 cm by 39 cm. How much heat flows through this window per minute if the inside and outside temperatures differ by 17 C∘? Express your answer using two significant figures.
A glass window 0.33 cm thick measures 87 cm by 36 cm. Part A How much heat flows through this window per minute if the inside and outside temperatures differ by 14 C∘?Express your answer using two significant figures.
A glass window 0.35 cm thick measures 85 cm by 35 cm . If the inside and outside temperatures differ by 17 ∘, the heat flows through this window per minute is 73 kJ . Part A To compare the relative efficiency of air and glass as insulators, calculate the heat flows through this window per minute with a 0.35 cm thick layer of air instead of glass. Part B By what factor is the rate of heat transfer reduced?
A glass windowpane in a home is 0.62 cm thick and has dimensions of 1.4 m × 1.6 m. On a certain day, the indoor temperature is 24°C and the outdoor temperature is 0°C. (a) What is the rate at which energy is transferred by heat through the glass? ________W (b) How much energy is lost through the window in one day, assuming the temperatures inside and outside remain constant? _________ J
How much heat per square meter is conducted in one hour through a 0.64 cm thick window pane when the inside temperature is 22o C and the outside temperature is 0o C ? Answer: 9.9x10^6 J How to solve?
CHP 11 A glass windowpane in a home is 0.62 cm thick and has dimensions of 1.2 m × 2.2 m. On a certain day, the indoor temperature is 20°C and the outdoor temperature is 0°C. (a) What is the rate at which energy is transferred by heat through the glass? W (b) How much energy is lost through the window in one day, assuming the temperatures inside and outside remain constant? J
A Thermopane window consists of two glass panes, each 0.50 cm thick, with a 1.0 cm thick sealed layer of air between. If the inside temperature is 22.0°C and the outside temperature is 0.0°C, determine the rate of heat transfer through 1.0 m2 of the window. Compare this with the rate of heat transfer through 1.0 m2 of a single 1.0 cm thick pane of glass.
A Thermopane window consists of two glass panes, each 0.50 cm thick, with a 1.0 cm thick sealed layer of air between. If the inside temperature is 23.5°C and the outside temperature is 0.0°C, determine the rate of heat transfer through 2.0 m2 of the window. Compare this with the rate of heat transfer through 2.0 m2 of a single 1.0 cm thick pane of glass. J/s (Thermopane window) J/s (Single pane window)
(a) Calculate the rate of heat conduction (in W) through a double-paned window that has a 5.00 m2 area and is made of two panes of 0.700 cm thick glass separated by a 1.00 cm air gap. The inside surface temperature is 17.0°C, while that on the outside is −20.0°C. (Hint: There are identical temperature drops across the two glass panes. First find these and then the temperature drop across the air gap. This problem ignores the increased heat transfer...
