what is the height of hockey goal post
Field hockey pitch Goals consist of two upright posts placed equidistant from the centre of the backline, joined at the top by a horizontal crossbar. The inner edges of the posts must be 3.66 metres (4 yd) apart, and the lower edge of the crossbar must be 2.14 metres (7 ft) above the ground. The goalposts and crossbar must be white and rectangular in shape with width 50 millimetres (2 in) and a depth of 50 to 75 millimetres (2 to 3 in).
Ice rink Modern rinks have a specific procedure for preparing the surface. With the pipes cold, a thin layer of water is sprayed on the sand or concrete to seal and level it (or in the case of concrete, to keep it from being marked). This thin layer is painted white or pale blue for better contrast; markings necessary for hockey or curling are also placed, along with logos or other decorations. Another thin layer of water is sprayed on top of this. The ice is built up to a thickness of 3/4ths an inch to 1 1/2 inches.[9] The industry standard in the NHL is around 1 1/2".
