Skate slides over the ice because the skate blade exerts sufficient pressure. Determine the pressure an ice skate blade must exert to allow a smooth ice skate at - 20°C. Below data are given for the range of temperatures and pressures involved: AH fus,ice =780 kJ/kg; V jig = 1x10 m³/kg and Vce = 1.01x 103 m³/kg. ice Answer: : (bar).
