The theoretical heat load produced by the pressure drop across the umbilical of 1,000 PSI (800 + 200 = 1,000) was 10.35 kW. This meant that the heat load of the umbilical was 0.35 kW more than the heat dissipation capacity of the hydraulic systemâs heat exchanger.
Currently, benefits can be payable as early as age 62, and the proposals to increase NRA often keep theearliest retirement age at 62.In 1983, Congress enacted increases in the NRA, partially recognizing the fact that life expectancyhas increased substantially since 1940.
