甲公司是一家制药企业。2008年，甲公司在现有产品P-Ⅰ的基础上成功研制出第二代产品P-Ⅱ。如果第二代产品投产，需要新购置成本为10000000元的设备一台，税法规定该设备使用期为5年，采用直线法计提折旧，预计残值率为5%。第5年年末，该设备预计市场价值为1000000元（假定第5年年末P-Ⅱ停产）。财务部门估计每年固定成本为600000元（不含折旧费），变动成本为200元/盒。另外，新设备投产初期需要投入净营运资金3000000元。净营运资金于第5年年末全额收回。新产品P-Ⅱ投产后，预计年销售量为50000盒，销售价格为300元/盒。同时，由于产品P-Ⅰ与新产品P-Ⅱ存在竞争关系，新产品P-Ⅱ投产后会使产品P-Ⅰ的每年经营现金净流量减少545000元。新产品P-Ⅱ项目的β系数为1.40甲公司的债务权益比为4：6（假设资本结构保持不变），债务融资成本为8%（税前）。甲公司适用的公司所得税税率为25%。资本市场中的无风险利率为4%，市场组合的预期报酬率为9%。假定经营现金流入在每年年末取得。
要求：
(1)计算产品P-Ⅱ投资决策分析时适用的折现率。
(2)计算产品P-Ⅱ投资的初始现金流量、第5年年末现金流量净额。
(3)计算产品P-Ⅱ投资的净现值。
