Question details

5. Snow begins falling continuously at midnight until 3:00 am at the rate of 0.7 lb/ft2-hr on the 34°F concrete. Sensors immediately detect this and turn on the heat pump snow melting system which supplies 1.5E5 BTU/hr to the slab. Assuming that the slab remains at 34°F and that no other heat is lost to the soil or surroundings, will the snow be melted before the morning commuter rush at 6:00 am? What fraction of it is left? Provide justification for your answers. Is snow melted: Units: yes/no Fraction of remaining snow: Units: percent
